system/gcc: Update to 13.3.0
0012-static-pie and 201-ada were forward-ported by my own paws. Three digit 0xx underscore patches are from Gentoo. This is also the source of the insn-split and match-split patches, which significantly increase performance on build. They are also the source of the new configure option --with-matchpd-partitions. On systems with very many cores/threads, a number higher than 32 would probably perform even better, but 32 should give decent perf on 8+ threads, and runs quite nicely on the 64-thread Talos II I ran the testbuild on. 202 is from Void. The 300s are originally written by me. The Ada patch now includes an improvement to use posix_openpt instead of getpt, which fixes link errors later on. We also now use STAGE1_CFLAGS and BOOT_CFLAGS to improve build times. Improvement was clocked from 40m to 32m (-8m, or 20%) on gwyn. The patch for Go name mangling is needed to build packages that use reflect2, which includes user/gitlab-runner.

+Since we have interest in an eventual Alpha port, it seems good to add this
+patch to our patchset now. The original patch comes from Gentoo, and like
+them, we would like to see packages behave consistently across our various
+architectures.
+
+Original Gentoo patch content follows.
+
+--
+
+Set the default behavior on alpha to use -mieee since the large majority of
+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.

+Subject: [PATCH 03/15] match.pd: CSE the dump output check.
+
+This is a small improvement in QoL codegen for match.pd to save time not
+re-evaluating the condition for printing debug information in every function.
+
+There is a small but consistent runtime and compile time win here. The runtime
+win comes from not having to do the condition over again, and on Arm plaforms
+we now use the new test-and-branch support for booleans to only have a single
+instruction here.

+Subject: [PATCH] Fix riscv_expand_conditional_move.
+
+Two issues have been observed in current riscv_expand_conditional_move
+implementation.
+1. Before introduction of TARGET_XTHEADCONDMOV, op0 of comparision expression
+is used for mode comparision with word_mode, but after TARGET_XTHEADCONDMOV
+megered with TARGET_SFB_ALU, dest of if-then-else is used for mode comparision with
+word_mode, and from md file mode of dest is DI or SI which can be different with
+word_mode in RV64.
+
+2. TARGET_XTHEADCONDMOV cannot be generated when the mode of the comparison is E_VOID.
+
+This patch solves the issues above.
+
+Provide an example from the newly added test case.
+
+Testcase:
+int ConNmv_reg_reg_reg(int x, int y, int z, int n){
+ if (x != y) return z;
+ return n;
+}
+
+Cflags:
+-O2 -march=rv64gc_xtheadcondmov -mabi=lp64d
+
+before patch:
+ConNmv_reg_reg_reg:
+ bne a0,a1,.L23
+ mv a2,a3
+.L23:
+ mv a0,a2
+ ret
+

+Subject: [PATCH 13/15] genemit: Split insn-emit.cc into ten files.
+
+After working with Sam off-list (thanks) I managed to get hppa to
+build. Initially it looked as if hppa just had a very small number of
+instruction patterns so we wouldn't generate all 10 output files.
+However, the actual issue (which we will only hit with a low
+pattern count) was with counting all the patterns vs only counting
+the patterns that will be output. A wrong pattern count lead to
+prematurely stopping to write output files.
+
+With that corrected, hppa "just works" until I hit linker errors
+due to relocations - most likely unrelated:
+
+bin/ld: unwind-dw2-fde-dip_s.o(.data.rel.ro+0): cannot handle
+R_PARISC_FPTR64 for __pthread_key_create@@GLIBC_2.34
+
+Attached is v3 that has been bootstrapped and tested on x86 and power10,
+aarch64 bootstrap was ok, testsuite is still running. A riscv build and
+testsuite run was successful as well.
+
+Regards
+ Robin

+Subject: [PATCH v3] genemit: Split insn-emit.cc into several partitions.
+
+On riscv insn-emit.cc has grown to over 1.2 mio lines of code and
+compiling it takes considerable time.
+Therefore, this patch adjust genemit to create several partitions
+(insn-emit-1.cc to insn-emit-n.cc). The available patterns are
+written to the given files in a sequential fashion.
+
+Similar to match.pd a configure option --with-emitinsn-partitions=num
+is introduced that makes the number of partition configurable.

+Subject: [PATCH 04/15] genmatch: split shared code to gimple-match-exports.cc
+
+In preparation for automatically splitting match.pd files I split off the
+non-static helper functions that are shared between the match.pd functions off
+to another file.
+
+This file can be compiled in parallel and also allows us to later avoid
+duplicate symbols errors.
+
+gcc/ChangeLog:
+
+ PR bootstrap/84402
+ * Makefile.in (OBJS): Add gimple-match-exports.o.
+ * genmatch.cc (decision_tree::gen): Export gimple_gimplify helpers.
+ * gimple-match-head.cc (gimple_simplify, gimple_resimplify1,
+ gimple_resimplify2, gimple_resimplify3, gimple_resimplify4,
+ gimple_resimplify5, constant_for_folding, convert_conditional_op,
+ maybe_resimplify_conditional_op, gimple_match_op::resimplify,
+ maybe_build_generic_op, build_call_internal, maybe_push_res_to_seq,
+ do_valueize, try_conditional_simplification, gimple_extract,
+ gimple_extract_op, canonicalize_code, commutative_binary_op_p,
+ commutative_ternary_op_p, first_commutative_argument,
+ associative_binary_op_p, directly_supported_p,
+ get_conditional_internal_fn): Moved to gimple-match-exports.cc
+ * gimple-match-exports.cc: New file.

+Subject: [PATCH 05/15] match.pd: automatically partition *-match.cc files.
+
+Following on from Richi's RFC[1] this is another attempt to split up match.pd
+into multiple gimple-match and generic-match files. This version is fully
+automated and requires no human intervention.
+
+First things first, some perf numbers. The following shows the effect of the
+patch on my desktop doing parallel compilation of gimple-match:

++--------+------------------+--------+------------------+
+
+As can be seen there seems to be a point of diminishing returns in doing splits.
+This comes from the fact that these match files consume a sizeable amount of
+headers. At a certain point the parsing overhead of the headers dominate and
+you start losing in gains.
+
+As such from this I've made the default 10 splits per file to allow for some
+room for growth in the future without needing changes to the split amount.
+Since 5-10 show roughly the same gains it means we can afford to double the
+file sizes before we need to up the split amount. This can be controlled
+by the configure parameter --with-matchpd-partitions=.
+
+At 10 splits the sizes of the files are:
+
+ 1.2M gimple-match-1.cc
+ 490K gimple-match-2.cc
+ 459K gimple-match-3.cc
+ 462K gimple-match-4.cc
+ 466K gimple-match-5.cc
+ 690K gimple-match-6.cc
+ 517K gimple-match-7.cc
+ 693K gimple-match-8.cc
+1011K gimple-match-9.cc
+ 490K gimple-match-10.cc
+ 210K gimple-match-auto.h
+
+The reason gimple-match-1.cc is so large is because it got allocated a very
+large function: gimple_simplify_NE_EXPR.
+
+Because of these sporadically large functions the allocation to a split happens
+based on the amount of data already written to a split instead of just a simple
+round robin allocation (though the patch supports that too.). This means that
+once gimple_simplify_NE_EXPR is allocated to gimple-match-1.cc nothing uses it
+again until the rest of the files catch up.
+
+To support this split a new header file *-match-auto.h is generated to allow
+the individual files to compile separately.
+
+Lastly for the auto generated files I use pragmas to silence the unused
+predicate warnings instead of the previous Makefile way because I couldn't find
+a way to set them without knowing the number of split files beforehand.
+
+Finally with this change, bootstrap time has dropped 8 minutes on AArch64.

+Subject: [PATCH 06/15] match.pd: Use splits in makefile and make configurable.
+
+This updates the build system to split up match.pd files into chunks of 10.
+This also introduces a new flag --with-matchpd-partitions which can be used to
+change the number of partitions.
+
+For the analysis of why 10 please look at the previous patch in the series.

+Subject: [PATCH 07/15] Makefile.in: clean up match.pd-related dependencies
+
+Clean up confusing changes from the recent refactoring for
+parallel match.pd build.
+
+gimple-match-head.o is not built. Remove related flags adjustment.
+
+Autogenerated gimple-match-N.o files do not depend on
+gimple-match-exports.cc.
+
+{gimple,generic)-match-auto.h only depend on the prerequisites of the
+corresponding s-{gimple,generic}-match stamp file, not any .cc file.
+
+gcc/ChangeLog:
+
+ * Makefile.in: (gimple-match-head.o-warn): Remove.
+ (GIMPLE_MATCH_PD_SEQ_SRC): Do not depend on
+ gimple-match-exports.cc.
+ (gimple-match-auto.h): Only depend on s-gimple-match.
+ (generic-match-auto.h): Likewise.
+

+Subject: [PATCH 08/15] build: Replace seq for portability with GNU Make
+ variant
+
+Some hosts like AIX don't have seq command, this patch replaces it
+with something that uses just GNU make features we've been using
+for this already before for the parallel make check.
+
+2023-05-06 Jakub Jelinek <jakub@redhat.com>
+
+ * Makefile.in (check_p_numbers): Rename to one_to_9999, move
+ earlier with helper variables also renamed.
+ (MATCH_SPLUT_SEQ): Use $(wordlist 1,$(NUM_MATCH_SPLITS),$(one_to_9999))
+ instead of $(shell seq 1 $(NUM_MATCH_SPLITS)).
+ (check_p_subdirs): Use $(one_to_9999) instead of $(check_p_numbers).
