+From: Pan Li <pan2.li@intel.com>
+
+When enabled the PHI handing for COND_EXPR,  we need to insert the gcall
+to replace the PHI node.  Unfortunately,  I made a mistake that insert
+the gcall to before the last stmt of the bb.  See below gimple,  the PHI
+is located at no.1 but we insert the gcall (aka no.9) to the end of
+the bb.  Then the use of _9 in no.2 will have no def and will trigger
+ICE when verify_ssa.
+
+  1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
+  2. prephitmp_36 = (char *) _9;
+  3. buf.write_base = string_13(D);
+  4. buf.write_ptr = string_13(D);
+  5. buf.write_end = prephitmp_36;
+  6. buf.written = 0;
+  7. buf.mode = 3;
+  8. _7 = buf.write_end;
+  9. _9 = .SAT_ADD (string.0_2, maxlen_15(D));   // Insert gcall to last bb by mistake
+
+This patch would like to insert the gcall to before the start of the bb
+stmt.  To ensure the possible use of PHI_result will have a def exists.
+After this patch the above gimple will be:
+
+  0. _9 = .SAT_ADD (string.0_2, maxlen_15(D));   // Insert gcall to start bb by mistake
+  1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
+  2. prephitmp_36 = (char *) _9;
+  3. buf.write_base = string_13(D);
+  4. buf.write_ptr = string_13(D);
+  5. buf.write_end = prephitmp_36;
+  6. buf.written = 0;
+  7. buf.mode = 3;
+  8. _7 = buf.write_end;
+
+The below test suites are passed for this patch:
+* The rv64gcv fully regression test with newlib.
+* The rv64gcv build with glibc.
+* The x86 regression test with newlib.
+* The x86 bootstrap test with newlib.
+
+	PR target/115387
+
+gcc/ChangeLog:
+
+	* tree-ssa-math-opts.cc (math_opts_dom_walker::after_dom_children): Take
+	the gsi of start_bb instead of last_bb.
+
+gcc/testsuite/ChangeLog:

+Subject: [PATCH] tree-optimization/115395 - wrong-code with SLP reduction in
+ epilog
+
+When we continue a non-SLP reduction from the main loop in the
+epilog with a SLP reduction we currently fail to handle an
+adjustment by the initial value because that's not a thing with SLP.
+As long as we have the possibility to mix SLP and non-SLP we have
+to handle it though.
+
+	PR tree-optimization/115395
+	* tree-vect-loop.cc (vect_create_epilog_for_reduction):
+	Handle STMT_VINFO_REDUC_EPILOGUE_ADJUSTMENT also for SLP
+	reductions of group_size one.
+
+	* gcc.dg/vect/pr115395.c: New testcase.

-When enabled the PHI handing for COND_EXPR,  we need to insert the gcall
-to replace the PHI node.  Unfortunately,  I made a mistake that insert
-the gcall to before the last stmt of the bb.  See below gimple,  the PHI
-is located at no.1 but we insert the gcall (aka no.9) to the end of
-the bb.  Then the use of _9 in no.2 will have no def and will trigger
-ICE when verify_ssa.
-
-  1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
-  2. prephitmp_36 = (char *) _9;
-  3. buf.write_base = string_13(D);
-  4. buf.write_ptr = string_13(D);
-  5. buf.write_end = prephitmp_36;
-  6. buf.written = 0;
-  7. buf.mode = 3;
-  8. _7 = buf.write_end;
-  9. _9 = .SAT_ADD (string.0_2, maxlen_15(D));   // Insert gcall to last bb by mistake
-
-This patch would like to insert the gcall to before the start of the bb
-stmt.  To ensure the possible use of PHI_result will have a def exists.
-After this patch the above gimple will be:
-
-  0. _9 = .SAT_ADD (string.0_2, maxlen_15(D));   // Insert gcall to start bb by mistake
-  1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
-  2. prephitmp_36 = (char *) _9;
-  3. buf.write_base = string_13(D);
-  4. buf.write_ptr = string_13(D);
-  5. buf.write_end = prephitmp_36;
-  6. buf.written = 0;
-  7. buf.mode = 3;
-  8. _7 = buf.write_end;
-
-The below test suites are passed for this patch:
-* The rv64gcv fully regression test with newlib.
-* The rv64gcv build with glibc.
-* The x86 regression test with newlib.
-* The x86 bootstrap test with newlib.
-

-
-	* tree-ssa-math-opts.cc (math_opts_dom_walker::after_dom_children): Take

+Content-Transfer-Encoding: 8bit
+
+René's patch seems to have stalled, so here is an updated version of the
+patch with the requested changes to his patch.
+
+I'll note I have added an additional code change, which is to also emit a
+".machine altivec" if Altivec is enabled.  The problem this fixes is for
+cpus like the G5, which is basically a power4 plus an Altivec unit, its
+".machine power4" doesn't enable the assembler to recognize Altivec insns.
+That isn't a problem if you use gcc -mcpu=G5 to assemble the assembler file,
+since gcc passes -maltivec to the assembler.  However, if you try to assemble
+the assembler file with as by hand, you'll get "unrecognized opcode" errors.
+I did not do the same for VSX, since all ".machine <cpu>" for cpus that
+support VSX already enable VSX insn recognition, so it's not needed.
+
+
+rs6000: Fix .machine cpu selection w/ altivec [PR97367]
+
+There are various non-IBM CPUs with altivec, so we cannot use that
+flag to determine which .machine cpu to use, so ignore it.
+Emit an additional ".machine altivec" if Altivec is enabled so
+that the assembler doesn't require an explicit -maltivec option
+to assemble any Altivec instructions for those targets where
+the ".machine cpu" is insufficient to enable Altivec.  For example,
+-mcpu=G5 emits a ".machine power4".
+
+This passed bootstrap and regtesting on powrpc64-linux (running the testsuite
+in both 32-bit and 64-bit modes) with no regressions.
+
+Ok for trunk and the release branches after some trunk burn-in time?

15.0.0: re-enable -fext-dce at -O2

All known issues are fixed, let's get testing it again.

I have let Jeff know I spotted a test is failing on s390x at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115912#c21.

+
+These tests expect the diagnostic from -Wcomplain-wrong-lang but

+with -Wno-complain-wrong-lang.
+
+gcc/testsuite/ChangeLog:
+        * gfortran.dg/ISO_Fortran_binding_17.f90: Pass -Wcomplain-wrong-lang.
+        * gfortran.dg/c-interop/allocate-errors.f90: Likewise.

+        * gfortran.dg/c-interop/select-errors.f90: Likewise.

+Subject: [PATCH] genoutput: Accelerate the place_operands function.
+
+With the increase in the number of modes and patterns for some
+backend architectures, the place_operands function becomes a
+bottleneck int the speed of genoutput, and may even become a
+bottleneck int the overall speed of building the GCC project.
+This patch aims to accelerate the place_operands function,
+the optimizations it includes are:
+1. Use a hash table to store operand information,
+   improving the lookup time for the first operand.
+2. Move mode comparison to the beginning to avoid the scenarios of most strcmp.
+
+I tested the speed improvements for the following backends,
+	Improvement Ratio
+x86_64	197.9%
+aarch64	954.5%
+riscv	2578.6%
+If the build machine is slow, then this improvement can save a lot of time.
+
+I tested the genoutput output for x86_64/aarch64/riscv backends,
+and there was no difference compared to before the optimization,
+so this shouldn't introduce any functional issues.
+
+gcc/
+	* genoutput.cc (struct operand_data): Add member 'eq_next' to
+	point to the next member with the same hash value in the
+	hash table.
+	(compare_operands): Move the comparison of the mode to the very
+	beginning to accelerate the comparison of the two operands.
+	(struct operand_data_hasher): New, a class that takes into account
+	the necessary elements for comparing the equality of two operands
+	in its hash value.
+	(operand_data_hasher::hash): New.
+	(operand_data_hasher::equal): New.
+	(operand_datas): New, hash table of konwn pattern operands.
+	(place_operands): Use a hash table instead of traversing the array
+	to find the same operand.
+	(main): Add initialization of the hash table 'operand_datas'.

- factor_out_conditional_operation [PR116412]
-
-After the conversion to use maybe_push_res_to_seq, sometimes (REALPART_EXPR
-and IMAGPART_EXPR and VCE) the argument will not be a gimple value and
-then phiopt here would create an invalid PHI.
-Just add a check for gimple val is the way to fix this.
-
-Bootstrapped and tested on x86_64-linux-gnu.
-
-	PR tree-optimization/116412

-gcc/ChangeLog:
-
-	* tree-ssa-phiopt.cc (factor_out_conditional_operation): Make sure new_arg0
-	and new_arg1 are both gimple values.

+Subject: [PATCH] Fix bootstap-errors due to enabling -gvariable-location-views
+
+This recent change triggered various bootsteap-errors, mostly on
+x86 targets because line info advance address entries were output
+in the wrong section table.
+The switch to the wrong line table happened in dwarfout_set_ignored_loc.
+It must use the same section as the earlier called
+dwarf2out_switch_text_section.
+
+But also ft32-elf was affected, because the assembler choked on
+something simple as ".2byte .LM2-.LM1", but fortunately it is
+able to use native location views, the configure test was just
+not executed because the ft32 "nop" instruction was missing.
+
+gcc/ChangeLog:
+
+PR debug/116470
+	* configure.ac: Add the "nop" instruction for cpu type ft32.
+	* configure: Regenerate.
+	* dwarf2out.cc (dwarf2out_set_ignored_loc): Use the correct
+	line info section.

+ [PR116348]
+
+After fixing PR116142 some code started to trigger an ICE with -O3
+-march=znver4.  Per Richard Biener who actually made this fix:
+
+"supportable_widening_operation fails at transform time - that's likely
+because vectorizable_reduction "puns" defs to internal_def"
+
+so the check should use STMT_VINFO_REDUC_DEF instead of checking if
+STMT_VINFO_DEF_TYPE is vect_reduction_def.
+
+gcc/ChangeLog:
+
+	PR tree-optimization/PR116348
+	* tree-vect-stmts.cc (supportable_widening_operation): Use
+	STMT_VINFO_REDUC_DEF (x) instead of
+	STMT_VINFO_DEF_TYPE (x) == vect_reduction_def.
+
+gcc/testsuite/ChangeLog:
+

-Subject: [PATCH] Fix bootstap-errors due to enabling -gvariable-location-views
-
-This recent change triggered various bootsteap-errors, mostly on
-x86 targets because line info advance address entries were output
-in the wrong section table.
-The switch to the wrong line table happened in dwarfout_set_ignored_loc.
-It must use the same section as the earlier called
-dwarf2out_switch_text_section.
-
-But also ft32-elf was affected, because the assembler choked on
-something simple as ".2byte .LM2-.LM1", but fortunately it is
-able to use native location views, the configure test was just
-not executed because the ft32 "nop" instruction was missing.
-
-gcc/ChangeLog:
-
-PR debug/116470
-	* configure.ac: Add the "nop" instruction for cpu type ft32.
-	* configure: Regenerate.
-	* dwarf2out.cc (dwarf2out_set_ignored_loc): Use the correct
-	line info section.

-Subject: [PATCH] vect: Fix STMT_VINFO_DEF_TYPE check for odd/even widen mult
- [PR116348]
-
-After fixing PR116142 some code started to trigger an ICE with -O3
--march=znver4.  Per Richard Biener who actually made this fix:
-
-"supportable_widening_operation fails at transform time - that's likely
-because vectorizable_reduction "puns" defs to internal_def"
-
-so the check should use STMT_VINFO_REDUC_DEF instead of checking if
-STMT_VINFO_DEF_TYPE is vect_reduction_def.
-
-gcc/ChangeLog:
-
-	PR tree-optimization/PR116348
-	* tree-vect-stmts.cc (supportable_widening_operation): Use
-	STMT_VINFO_REDUC_DEF (x) instead of
-	STMT_VINFO_DEF_TYPE (x) == vect_reduction_def.
-
-gcc/testsuite/ChangeLog:
-
-	PR tree-optimization/PR116348
-	* gcc.c-torture/compile/pr116438.c: New test.

+Subject: [PATCH] middle-end: check explicitly for external or constants when
+ checking for loop invariant [PR116817]
+
+Hi All,
+
+The previous check if a value was external was checking
+!vect_get_internal_def (vinfo, var) but this of course isn't completely right
+as they could reductions etc.
+
+This changes the check to just explicitly look at externals and constants.
+Note that reductions remain unhandled here, but we don't support codegen of
+boolean reductions today anyway.
+
+So at the time we do then this would have the be handled as well in lowering.
+
+Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
+
+Ok for master?
+
+Thanks,
+Tamar

-Subject: [PATCH] middle-end: check explicitly for external or constants when
- checking for loop invariant [PR116817]
-
-Hi All,
-
-The previous check if a value was external was checking
-!vect_get_internal_def (vinfo, var) but this of course isn't completely right
-as they could reductions etc.
-
-This changes the check to just explicitly look at externals and constants.
-Note that reductions remain unhandled here, but we don't support codegen of
-boolean reductions today anyway.
-
-So at the time we do then this would have the be handled as well in lowering.
-
-Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
-
-Ok for master?
-
-Thanks,
-Tamar

-Subject: [PATCH 2/2] c++: Return the underlying decl rather than the
- USING_DECL from update_binding [PR116913]
-
-Users of pushdecl assume that the returned decl will be a possibly
-updated decl matching the one that was passed in.  My r15-3910 change
-broke this since in some cases we would now return USING_DECLs; this
-patch fixes the situation.
-
-	PR c++/116913
-
-gcc/cp/ChangeLog:
-
-	* name-lookup.cc (update_binding): Return the strip_using'd old
-	decl rather than the binding.
-
-gcc/testsuite/ChangeLog:
-
-	* g++.dg/lookup/using70.C: New test.

+Subject: [PATCH] c++, coroutines: Fix awaiter var creation [PR116506].
+
+Awaiters always need to have a coroutine state frame copy since
+they persist across potential supensions.  It simplifies the later
+analysis considerably to assign these early which we do when
+building co_await expressions.
+
+The cleanups in r15-3146-g47dbd69b1, unfortunately elided some of
+processing used to cater for cases where the var created from an
+xvalue, or is a pointer/reference type.
+
+Corrected thus.
+
+	PR c++/116506
+	PR c++/116880
+
+gcc/cp/ChangeLog:
+
+	* coroutines.cc (build_co_await): Ensure that xvalues are
+	materialised.  Handle references/pointer values in awaiter
+	access expressions.
+
+gcc/testsuite/ChangeLog:
+
+	* g++.dg/coroutines/pr116506.C: New test.
+	* g++.dg/coroutines/pr116880.C: New test.

+Subject: [PATCH] c: Fix up speed up compilation of large char array
+ initializers when not using #embed [PR117177]
+
+Hi!
+
+Apparently my
+c: Speed up compilation of large char array initializers when not using #embed
+patch broke building glibc.
+
+The issue is that when using CPP_EMBED, we are guaranteed by the
+preprocessor that there is CPP_NUMBER CPP_COMMA before it and
+CPP_COMMA CPP_NUMBER after it (or CPP_COMMA CPP_EMBED), so RAW_DATA_CST
+never ends up at the end of arrays of unknown length.
+Now, the c_parser_initval optimization attempted to preserve that property
+rather than changing everything that e.g. inferes array number of elements
+from the initializer etc. to deal with RAW_DATA_CST at the end, but
+it didn't take into account the possibility that there could be
+CPP_COMMA followed by CPP_CLOSE_BRACE (where the CPP_COMMA is redundant).
+
+As we are peaking already at 4 tokens in that code, peeking more would
+require using raw tokens and that seems to be expensive doing it for
+every pair of tokens due to vec_free done when we are out of raw tokens.
+
+So, the following patch instead determines the case where we want
+another INTEGER_CST element after it after consuming the tokens, and just
+arranges for another process_init_element.
+
+Ok for trunk if this passes bootstrap/regtest?

+
+Sorry for rushing the previous patch too much, turns out I was wrong,
+given that the c_parser_peek_nth_token numbering is 1 based, we can peek
+also with c_parser_peek_nth_token (parser, 4) and the loop actually peeked
+just at 3 tokens, not 4.
+
+So, I think it is better to revert the previous patch (but keep the new
+test) and instead peek the 4th non-raw token, which is what the following
+patch does.
+
+Additionally, PR117190 shows one further spot which missed the peek of
+the token after CPP_COMMA, in case it is incomplete array with exactly 65
+elements with redundant comma after it, which this patch handles too.
+
+Bootstrapped/regtested on x86_64-linux, i686-linux, powerpc64le-linux
+and powerpc64-linux, ok for trunk?

+	* c-parser.cc (c_parser_initval): Revert 2024-10-17 changes.
+	Instead peek the 4th token and if it is not CPP_NUMBER,
+	handle it like 3rd token CPP_CLOSE_BRACE for orig_len == INT_MAX.
+	Also, check (2 + 2 * i)th raw token for the orig_len == INT_MAX

-Subject: [PATCH] c: Better fix for speed up compilation of large char array

-Sorry for rushing the previous patch too much, turns out I was wrong,
-given that the c_parser_peek_nth_token numbering is 1 based, we can peek
-also with c_parser_peek_nth_token (parser, 4) and the loop actually peeked
-just at 3 tokens, not 4.
-
-So, I think it is better to revert the previous patch (but keep the new
-test) and instead peek the 4th non-raw token, which is what the following
-patch does.
-
-Additionally, PR117190 shows one further spot which missed the peek of
-the token after CPP_COMMA, in case it is incomplete array with exactly 65
-elements with redundant comma after it, which this patch handles too.
-
-Bootstrapped/regtested on x86_64-linux, i686-linux, powerpc64le-linux
-and powerpc64-linux, ok for trunk?

-	Instead peek the 4th token and if it is not CPP_NUMBER,
-	handle it like 3rd token CPP_CLOSE_BRACE for orig_len == INT_MAX.
-	Also, check (2 + 2 * i)th raw token for the orig_len == INT_MAX

-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117493#c5
+After adding vn_valueize to the handle the `a | b ==/!= 0` case
+of insert_predicates_for_cond, it would go into an infinite loop
+as the Value number for either a or b could be the same as what it
+is for the whole expression. This avoids that recursion so there is
+no infinite loop here.
+
+Bootstrapped and tested on x86_64-linux.
+
+	PR tree-optimization/117496
+
+gcc/ChangeLog:
+
+	* tree-ssa-sccvn.cc (insert_predicates_for_cond): If the
+	valueization for the new lhs is the same as the old one,
+	don't recurse.

+Subject: [PATCH] match: Fix the `max<a,b>==0` pattern for pointers [PR117646]
+
+For pointers I forgot that BIT_IOR_EXPR is not valid so when
+I added the pattern to convert `max<a,b> != 0` (r15-5356), GCC
+would start to ICEing saying pointer types were not valid for
+BIT_IOR_EXPR.
+This fixes the problem by casting to the unsigned type of the
+inner type. There was another way of fixing this to handling it
+as `a == 0 & b == 0` but both match and reassoication (for pointers)
+will then convert it back into the form I am creating here so
+let's just use that form instead.
+
+Bootstrapped and tested on x86_64-linux-gnu.
+
+	PR tree-optimization/117646
+
+gcc/ChangeLog:
+
+	* match.pd (`max<a,b>==0`): Add casts to `unsigned type`.
+
+gcc/testsuite/ChangeLog:
+

+Subject: [PATCH] Default to -mfpmath=sse on x86 with time64
+
+Our time64 stages already default to `-mfpmath=sse`, so let's have
+the time64 flag implicitly enable it as the default to make things more
+consistent.  Furthermore, this also improves compatibility with clang
+that always enables it whenever the target architectures supports SSE.
+
+Note that this works only if `-march=` with SSE support is specified.
+We could technically improve the consistency even further by raising
+the default `-march=`, but that seems a bit intrusive and probably
+unnecessary, given that the vast majority of Gentoo users and/or
+upstream projects will specify `-march=`.

+Subject: [PATCH] genemit: Distribute evenly to files [PR111600].
+
+Hi,
+
+currently we distribute insn patterns in genemit, partitioning them
+by the number of patterns per file.  The first 100 into file 1, the
+next 100 into file 2, and so on.  Depending on the patterns this
+can lead to files of very uneven size.
+
+Similar to the genmatch split, this patch introduces a dynamic
+choose_output () which considers the size of the output files
+and selects the shortest one for the next pattern.
+
+Bootstrapped and regtested on x86 and power10, aarch64 running.
+Regtested on rv64gcv.
+
+gcc/ChangeLog:
+
+	PR target/111600
+
+* genemit.cc (handle_arg): Use files instead of filenames.
+	(main): Ditto.
+	* gensupport.cc (SIZED_BASED_CHUNKS): Define.
+	(choose_output): New function.
+	* gensupport.h (choose_output): Declare.
