I tried to reproduce it locally and did not succeed. Can you try a few tweaks to your defaults setup? > CFLAGS="-march=haswell -mtune=haswell -O3 -pipe" > CXXFLAGS="-march=haswell -mtune=haswell -O3 -pipe" 1. Does cross-compiler building fail the same with C{,XX}FLAGS="-O2 -pipe"? 2. Does cross-msp430-elf/gcc-8.2.0-r2 fail the same?
My apologies for the delay, I missed the update. 1. I ran: CFLAGS="-O2 -pipe" CXXFLAGS="-O2 -pipe" emerge -1av cross-msp430-elf/gcc with the same result. /var/tmp/portage/cross-msp430-elf/gcc-7.3.0-r3/work/gcc-7.3.0/libstdc++-v3/libsupc++/vec.cc: In function ‘std::size_t __cxxabiv1::{anonymous}::compute_size(std::size_t, std::size_t, std::size_t)’: /var/tmp/portage/cross-msp430-elf/gcc-7.3.0-r3/work/gcc-7.3.0/libstdc++-v3/libsupc++/vec.cc:67:41: internal compiler error: in simplify_subreg, at simplify-rtx.c:6014 if (element_size && element_count > std::size_t(-1) / element_size) ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I'll report back after #2 passes or fails.
Also, I should ask, do our USEs match? I've had to -sanitize -openmp -vtv -fortran from gcc in the past to get it to compile. I wouldn't be surprised if I need to remove more USE flag.
2. cross-msp430-elf/gcc-8.2.0-r2 compiles fine. So it appears to be a problem with 7.3.0-r3.
And finally, no big surprise, but 7.3.0-r4 doesn't work either.

I wouldn't be surprised > if I need to remove more USE flag. Oh, good point! I only now noticed I didn't have USE=cxx. I guess you did --stage4 crossdev install of this target (the default for bare-metal is --stage2). Now I've reproduced the failure as well.
Followed https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide and reduced to the following minimal test: $ cat vec.ii typedef __int20 unsigned a; int b, c(c > a(-1) / b); $ /tmp/portage/cross-msp430-elf/gcc-7.3.0-r4/work/build/./gcc/xgcc -B/tmp/portage/cross-msp430-elf/gcc-7.3.0-r4/work/build/gcc -mlarge -c vec.ii -o vec.o vec.ii: In function ‘void __static_initialization_and_destruction_0(int, int)’: vec.ii:2:12: internal compiler error: in simplify_subreg, at simplify-rtx.c:6014 int b, c(c > a(-1) / b); ~~^~~~~~~~~~~ Please submit a full bug report, with preprocessed source if appropriate. See <https://bugs.gentoo.org/> for instructions. Now bisecting gcc to see where it was fixed upstream.
Or the same without c++ involved: $ cat vec.i typedef __int20 unsigned a; d() { int b, c = c > (a)-1 / b; } $ /tmp/portage/cross-msp430-elf/gcc-7.3.0-r4/work/build/./gcc/xgcc -B/tmp/portage/cross-msp430-elf/gcc-7.3.0-r4/work/build/gcc -mlarge -c vec.i vec.i vec.i: In function ‘d’: vec.i:2:20: internal compiler error: in simplify_subreg, at simplify-rtx.c:6014
gcc-7 branch works, gcc-7.3.0 tag crashes. Bisected the fix down to: https://github.com/gcc-mirror/gcc/commit/59f5415b4462a60d9f2dd6dc5229247da183b9fc Which its an upstream fix of https://gcc.gnu.org/PR79242 Next gcc release will contain this fix. Fix looks trivial to pull into 7.3.0 as well.

The fix should be available in next gcc patchset bump. Meanwhile you can drop the patch https://gitweb.gentoo.org/proj/gcc-patches.git/plain/7.3.0/gentoo/98_all_msp430-partial-int.patch into /etc/portage/patches/cross-msp430-elf/gcc:7.3.0/ directory and test if gcc builds/works fine. Thanks for the report!
