+ (output_load_pcrel_sym): Declare. * config/sparc/sparc.c
+ (sparc_cannot_force_const_mem): Revert latest change.
+ (got_helper_needed): New static variable. (output_load_pcrel_sym): New
+ function. (get_pc_thunk_name): Remove after inlining...
+ (load_got_register): ...here. Rework the initialization of the GOT
+ register and of the GOT helper. (save_local_or_in_reg_p): Test the
+ REGNO of the GOT register. (sparc_file_end): Test got_helper_needed to
+ decide whether the GOT helper must be emitted. Use output_asm_insn
+ instead of fprintf. (sparc_init_pic_reg): In PIC mode, always initialize
+ the PIC register if optimization is enabled. *
+ config/sparc/sparc.md (load_pcrel_sym<P:mode>): Emit the assembly by
+ calling output_load_pcrel_sym.

9.2.0: drop 27_all_sparc-PIC-constant-PR91472.patch
PR91472 fixed obscure code generation bug on gmp testsuite but
introduced gcc regression in compiling python.
Let's revert the fix. It will break gmp tests on sparc again
but at least restore python building.

+Subject: [PATCH] driver: Also prune joined switches with negation
+
+When -march=native is passed to host_detect_local_cpu to the backend,
+it overrides all command lines after it. That means
+
+$ gcc -march=native -march=armv8-a
+
+is treated as
+
+$ gcc -march=armv8-a -march=native
+
+Prune joined switches with Negative and RejectNegative to allow
+-march=armv8-a to override previous -march=native on command-line.
+
+This is the same fix as was applied for i386 in SVN revision 269164 but for
+aarch64 and arm.

+
+While testing the fix for PR91068, I hit an rtl checking failure
+while building newlib. mips_split_move was decomposing an address that
+happened to be symbolic and then tried to access the REGNO of the base
+register field, which wasn't initialised but which by chance pointed to
+valid memory.

+time we want this (bad/weird things can happen with packages built without
+it).
+
+To satisfy those people who may not want -mieee forced on them all the time,
+we also provide -mno-ieee.
+
+Patch by Mike Frysinger <vapier@gentoo.org>
+
+Note: upstream doesn't want to take this due to long standing behavior, and
+because it'd make behavior across OS's inconsistent:
+ https://gcc.gnu.org/ml/gcc-patches/2003-07/msg02144.html
+
+This makes sense for upstream, but Gentoo is more concerned about packages
+behaving the same across arches under Linux.
