Module Name:    src
Committed By:   mrg
Date:           Fri Mar 27 00:29:30 UTC 2026

Modified Files:
        src/external/gpl3/gcc.old/dist/gcc: genmatch.cc
        src/tools/gcc: gcc-version.mk

Log Message:
genmatch.cc:  bring across several enhancements from mainline GCC.

in my testing this reduces the size of the emitted "gimple-match.cc"
by about 35%, reduces the code section sise about 15%, and reduces
the compile time about 30%.  (this file is the largest single compile
for all of GCC.)

this makes it capable of compiling on vax and sparc again, it seems,
where both were already capable for GCC 14 (which in addition to this
set, splits the emitted file into 10 sub parts for compiling both
separately and in parallel.)

(this is part 1, part 2 will be about mergig the split of the output
into multiple files, but may be abandoned as this portion helps
enough.)

tested on amd64, vax, sparc as only target, powerpc, with some arm64,
arm, and m68k to come -- may be also very useful for m68k target.

bump the netbsd gcc version.

XXX: pullup-11, but maybe afer netbsd 11.0 ships (my testing has been
largely against netbsd-11, so this option is well tested.)
