toolchain-funcs.eclass: Add tc-get-compiler-type()

Add a tc-get-compiler-type() function that can be used to identify
the compiler being used, using the preprocessor defines. Alike
gcc-*version() routines, it uses CPP (which in turn uses CC).

The major usage would be applying compiler-specific quirks and limiting
gcc version checks to compilers that actually are gcc, since e.g. clang
reports gcc version 4.2 -- which would incorrectly cause numerous gcc
version checks in ebuilds to fail.

toolchain-funcs.eclass: tc-ninja_magic_to_arch, remove old KV support

Remove the support for old kernel versions that are no longer used
in Gentoo, and rely on KV_to_int() function. This functions is provided
by Portage but not listed in PMS. Furthermore, for a long time Portage
replaced it with 'return 1' in global scope, so they did not really work
as expected anyway.

multiprocessing.eclass: Fix handling multiple short options (e.g. -kj)

Improve the regular expressions to handle parameters consisting of
multiple short options (such as -kj). It should be noted that the code
is not perfect but should handle all common (valid) cases; it could e.g.
incorrectly process a short option followed by string arg such as
'-Wfoo.j' although having this in MAKEOPTS is extremely unlikely.

multiprocess.eclass: makeopts_{jobs,loadavg}: fix implicit handling of $MAKEOPTS #608242

We missed quoting on ${MAKEOPTS} to set it as the first arg which meant
we might load invalid values into the second arg which is the "infinite"
scenario.

estack.eclass: Split estack* logic from eutils

Split the estack_* and related functions from eutils into a dedicated
estack.eclass. Those functions have significant complexity and are not
used frequently, therefore they benefit from having a separate file
and an explicit dedicated maintainer.

The new eclass is implicitly inherited by eutils to preserve
compatibility. However, the inherit will be removed in EAPI 7,
and the ebuilds should switch to using estack directly.

Thanks to Ulrich Müller for doing the research on this.

flag-o-matic.eclass: Strip LDFLAGS unsupported by the C compiler, #621274

Include LDFLAGS in the variables stripped by strip-unsupported-flags.
The code reuses the current functions for testing CC, and so only remove
LDFLAGS that are rejected by the C compiler and not the linker. This
solves the case of bug #621274 where LDFLAGS contained GCC-specific
-flto flag.

flag-o-matic.eclass: test-flag-PROG, ignore unused args in clang

By default, clang considers unused arguments as error when -Werror is
used. Since flag tests are performed without linking, this causes all
tests for linker flags to fail inadvertently and all those flags
are stripped as a result.

While the correctness of passing unused flags is doubtful, silently
stripping them in a few random packages is certainly not the solution
to the problem, and also makes the results differ between gcc and clang.
To account for that, use clang's -Qunused-arguments option to silence
unused argument warnings.

To avoid wasting time on testing the compiler, just try passing
-Qunused-arguments every time a flag check fails. If clang is not used,
the additional call will fail just the same as the previous one (either
because of the original flag or because of -Qunused-arguments), so
the result will be the same.

eapi7-ver.eclass: 'Early adopter' version of EAPI 7 version manip

EAPI 7 is introducing new version manipulation and comparison functions
that aim to replace versionator.eclass. This eclass provides an 'early
adopter' versions of those routines.

It serves two goals:

a. getting wider review and some real-life testing before
the specification is set in stone,

b. making it possible to adapt ebuilds to the new routines early,
reducing the future work of EAPI 7 porting,

c. improving cache generation speed (the rountines are roughly 15-20
times than versionator.eclass).

For more details on the new logic, please see the eclass documentation.
Long story short, we are introducing three functions:

1. ver_cut -- to get substrings of the version string,

2. ver_rs -- to replace version separators via indices,

3. ver_test -- to compare two version numbers.

The third function is not implemented in the eclass. It's meant to reuse
the algorithms from the package manager, and the final implementation
will most likely reuse the code from the package manager (e.g. via IPC).

The code has been initially written by Ulrich Müller.

+# @BLURB: Testing implementation of EAPI 7 version manipulators
+# @DESCRIPTION:
+# A stand-alone implementation of the version manipulation functions

+# the proposed functions and to allow ebuilds to switch to the new
+# model early, with minimal change needed for actual EAPI 7.

+#
+# @ROFF .SS
+# Version strings
+#
+# The functions support arbitrary version strings consisting of version
+# components interspersed with (possibly empty) version separators.
+#
+# A version component can either consist purely of digits ([0-9]+)
+# or purely of uppercase and lowercase letters ([A-Za-z]+).  A version
+# separator is either a string of any other characters ([^A-Za-z0-9]+),
+# or it occurs at the transition between a sequence of letters
+# and a sequence of digits, or vice versa.  In the latter case,
+# the version separator is an empty string.
+#
+# The version is processed left-to-right, and each successive component
+# is assigned numbers starting with 1.  The components are either split
+# on version separators or on boundaries between digits and letters
+# (in which case the separator between the components is empty).
+# Version separators are assigned numbers starting with 1 for
+# the separator between 1st and 2nd components.  As a special case,
+# if the version string starts with a separator, it is assigned index 0.
+#
+# Examples:
+#
+# @CODE
+#   1.2b-alpha4 -> 1 . 2 '' b - alpha '' 4
+#                  c s c s  c s c     s  c
+#                  1 1 2 2  3 3 4     4  5
+#
+#   .11.        -> . 11 .
+#                  s c  s
+#                  0 1  1
+# @CODE
+#
+# @ROFF .SS
+# Ranges
+#
+# A range can be specified as 'm' for m-th version component, 'm-'
+# for all components starting with m-th or 'm-n' for components starting
+# at m-th and ending at n-th (inclusive).  If the range spans outside
+# the version string, it is truncated silently.

eapi7-ver.eclass: Use lexicographic rather than arithmetic comparison.

This removes the 2**63-1 limit for integer components.

multiprocessing.eclass: Remove multijob_* functions

Remove the multijob functions that were used to run bash code
in parallel. The code was very complex, fragile and unmaintained. It has
been used scarcely, and pretty much by a single developer. It gave very
little gain, usually at the cost of losing readability and violating
PMS.

Closes: https://bugs.gentoo.org/613322

-# The multiprocessing eclass contains a suite of functions that allow ebuilds
-# to quickly run things in parallel using shell code.
+# The multiprocessing eclass contains a suite of utility functions
+# that could be helpful to controlling parallel multiple job execution.
+# The most common use is processing MAKEOPTS in order to obtain job
+# count.
 #
-# It has two modes: pre-fork and post-fork.  If you don't want to dive into any
-# more nuts & bolts, just use the pre-fork mode.  For main threads that mostly
-# spawn children and then wait for them to finish, use the pre-fork mode.  For
-# main threads that do a bit of processing themselves, use the post-fork mode.
-# You may mix & match them for longer computation loops.
 # @EXAMPLE:
 #
 # @CODE
-# # First initialize things:
-# multijob_init
-#
-# # Then hash a bunch of files in parallel:
-# for n in {0..20} ; do
-# 	multijob_child_init md5sum data.${n} > data.${n}

flag-o-matic.eclass: treat "--param x" as a unit when testing flags

For clang and gcc, --param consumes the next argument. Testing --param
and its value separately is nonsensical.

flag-o-matic.eclass: add LDFLAGS testing against linker

Before the change we tested only compiler driver (gcc flag parser)
for LDFLAGS.

This does not cover cases when we would really like to filter out
unsupported linker flags like -Wl,--hash-style=gnu passed to non-ELF
targets.

The change adds test-flag-CCLD() helper to perform all of assembly,
compilation and linking steps. Helper is used to filter LDFLAGS variable
in strip-unsupported-flags().

Closes: https://bugs.gentoo.org/333763

python-utils-r1.eclass: Remove PYTHON_TARGETS="pypy"

* With the EOL of CPython 2, we also want to
  remove support for PyPy (i.e. PyPy for Python 2).
  This change does not affect PyPy3, i.e. Pypy for
  Python 3.

* Python 3.5 will go EOL on 2020-09-13 and in order to reduce testing
  and maintenance burden, we want to keep the number of active Py3
  impls below four.

toolchain-funcs.eclass: fix or1k* tuple detection

Before the change the only recognised CHOST was 'or1k'.
After the change CHOSTs like 'or1k-linux-musl' are
also recognised as 'openrisc'.

python-utils-r1.eclass: Inline _python_impl_supported()

The _python_impl_supported() function is not used anymore in its
original function.  It is called only once, in order to die on incorrect
targets in PYTHON_COMPAT.  Let's inline the corresponding logic
in _python_set_impls() and remove the function.

While at it, add an extra check for outdated patterns.  This also
renders the relevant tests obsolete.

python-utils-r1.eclass: Deprecated and EAPI8-ban python_is_python3

There is no use for python_is_python3 anymore, as Python 2 is no longer
supported at runtime and the remaining any-r1 uses are pure-2.

multiprocessing.eclass: Default makeopts_jobs to inf=nproc+1

Change the default value for 'inf' argument to makeopts_jobs from 999
to $(get_nproc) + 1.  This means that if MAKEOPTS specifies a `-j`
argument without a specific value, nproc will be used rather than
infinity-ish number of jobs.

The old default made sense for ebuilds using both makeopts_jobs
and makeopts_loadavg.  However, these are very rare — only 4 packages
and 3 eclass at this time.  For the remaining ebuilds, they meant
uncontrollably using up to 999 jobs.

The new default is both safer and more correct for the vast majority
of Gentoo packages, removing the necessity of repeating:

    $(makeopts_jobs "${MAKEOPTS}" "$(get_nproc)")

The ebuilds and eclasses using makeopts_loadavg have been updated
to pass the old default.

by the current C compiler.  Currently it supports compiler-rt
and libgcc.

cargo.eclass: Add variable alternative to $(cargo_crate_uris)

Add a helper function that sets ${CARGO_CRATE_URIS} variable to make
it possible to set SRC_URI without subshells.  This gives a slight
speedup (~20%):

```
real  300 it/s
user  324 it/s
```

cargo.eclass: Support separating crate names/versions via `@`

Support specifying crate names and versions separated by `@` character
rather than `-`.  Since `@` are not valid in crate names, this
makes splitting the tokens trivial and free of regular expressions.
Effectively, the `@` variant is roughly 180% faster:

```
 * CRATES with '@' separator
real  952 it/s
user  952 it/s
 * CRATES with '-' separator
real  339 it/s
user  339 it/s
```

llvm-utils.eclass: Introduce an eclass for common helpers

Move some reusable functions from llvm.eclass to llvm-utils.eclass.
This is with minimal modifications so far (only argument checks were
cleaned up).

+# 3. Use llvm-r1_pkg_setup, get_llvm_prefix or LLVM_SLOT.

+# if no stable slots are supported) is enabled by default.

+# @CODE
+# LLVM_COMPAT=( {16..18} )
