Created attachment 399082 [details] emerge --info trying to build gcc-4.7.4 with x32 support isn't working. rather than try and fix this up, lets just drop it. the x32 support in 4.7 was always unofficial and done pending 4.8+ releases. now that those are in the stable tree, there's no reason to maintain the 4.7 support. specifically, it leads to ICEs: make[5]: Entering directory '/var/tmp/portage/sys-devel/gcc-4.7.4/work/build/x86_64-pc-linux-gnu/x32/libgcc' /var/tmp/portage/sys-devel/gcc-4.7.4/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.7.4/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include -O2 -march=amdfam10 -pipe -g -Wimplicit-function-declaration -mx32 -O2 -O2 -march=amdfam10 -pipe -g -Wimplicit-function-declaration -DIN_GCC -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -fpic -I. -I. -I../../.././gcc -I/var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc -I/var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/. -I/var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/../gcc -I/var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/../include -I/var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/config/libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS -DUSE_TLS -o unwind-dw2.o -MT unwind-dw2.o -MD -MP -MF unwind-dw2.dep -fexceptions -c /var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/unwind-dw2.c -fvisibility=hidden -DHIDE_EXPORTS /var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/unwind-dw2.c: In function ‘uw_frame_state_for’: /var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/unwind-dw2.c:1231:1: error: unrecognizable insn: (insn 97 96 98 9 (parallel [ (set (reg:SI 333) (const_int 0 [0])) (set (reg:SI 327) (plus:SI (ashift:SI (reg:SI 333) (const_int 3 [0x3])) (reg:SI 327))) (set (mem:BLK (reg:SI 327) [0 A8]) (const_int 0 [0])) (use (reg:DI 329)) (use (reg:SI 333)) ]) /usr/include/bits/string3.h:90 -1 (nil)) /var/tmp/portage/sys-devel/gcc-4.7.4/work/gcc-4.7.4/libgcc/unwind-dw2.c:1231:1: internal compiler error: in extract_insn, at recog.c:2123 Please submit a full bug report, with preprocessed source if appropriate.
