Try again with sane CFLAGS (glibc and gcc). libitm can get touchy when you override -m flags.
Hi, well, 'sane CFlags'... since I started with Gentoo that's the way I set my CFlags: 1) I run # echo "" | gcc -march=native -v -E - 2>&1 | grep cc1 On my test system this will output /usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.2/cc1 -E -quiet -v - -march=core-avx-i -mcx16 -msahf -mno-movbe -maes -mpclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mavx -mno-avx2 -msse4.2 -msse4.1 -mno-lzcnt -mno-rtm -mno-hle -mrdrnd -mf16c -mfsgsbase -mno-rdseed -mno-prfchw -mno-adx -mfxsr -mxsave -mxsaveopt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192 -mtune=core-avx-i 2) I use the march value from the first output for the second command: # echo "int main() { return 0; }" | gcc -march=core-avx-i -v -Q -x c - 2>&1 On my system this will be the output: [...] options enabled: -faggressive-loop-optimizations -fasynchronous-unwind-tables -fauto-inc-dec -fbranch-count-reg -fcommon -fdelete-null-pointer-checks -fdwarf2-cfi-asm -fearly-inlining -feliminate-unused-debug-types -ffunction-cse -fgcse-lm -fgnu-runtime -fident -finline-atomics -fira-hoist-pressure -fira-share-save-slots -fira-share-spill-slots -fivopts -fkeep-static-consts -fleading-underscore -fmath-errno -fmerge-debug-strings -fmove-loop-invariants -fpeephole -fprefetch-loop-arrays -freg-struct-return -fsched-critical-path-heuristic -fsched-dep-count-heuristic -fsched-group-heuristic -fsched-interblock -fsched-last-insn-heuristic -fsched-rank-heuristic -fsched-spec -fsched-spec-insn-heuristic -fsched-stalled-insns-dep -fshow-column -fsigned-zeros -fsplit-ivs-in-unroller -fstrict-volatile-bitfields -fsync-libcalls -ftrapping-math -ftree-coalesce-vars -ftree-cselim -ftree-forwprop -ftree-loop-if-convert -ftree-loop-im -ftree-loop-ivcanon -ftree-loop-optimize -ftree-parallelize-loops= -ftree-phiprop -ftree-pta -ftree-reassoc -ftree-scev-cprop -ftree-slp-vectorize -ftree-vect-loop-version -funit-at-a-time -funwind-tables -fvar-tracking -fvar-tracking-assignments -fzero-initialized-in-bss -m128bit-long-double -m64 -m80387 -maccumulate-outgoing-args -maes -malign-stringops -mavx -mavx256-split-unaligned-load -mavx256-split-unaligned-store -mcx16 -mf16c -mfancy-math-387 -mfp-ret-in-387 -mfsgsbase -mfxsr -mglibc -mieee-fp -mlong-double-80 -mmmx -mpclmul -mpopcnt -mpush-args -mrdrnd -mred-zone -msahf -msse -msse2 -msse3 -msse4 -msse4.1 -msse4.2 -mssse3 -mtls-direct-seg-refs -mxsave -mxsaveopt [...] From what I have learned, the second command shows the default options GCC will set based on the chosen march value. Therefore I'll compare the options from the first output with the options from the second output and remove redundant options. So for my system, I'll end with "-march=core-avx-i -mno-movbe -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mno-avx2 -mno-lzcnt -mno-rtm -mno-hle -mno-rdseed -mno-prfchw -mno-adx --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192 -mtune=generic" Is my approach wrong? However, for testing I set CFlags to "-march=core-avx-i -O2 -pipe" like you asked me to do and gcc-4.8.2 now builds again. I restored my previous CFlags and after multiple attempts to build gcc I found the CFlag which seems to cause my problems: "-mno-rtm" When "-mno-rtm" is set, sys-devel/gcc-4.8.2 will fail with this error. Without this CFlag, everything works fine. I am wondering because the first command indicates that GCC would set this CFlag... Feel free to close this bug if you think that's not gcc/package bug. Thanks! PS: The failing system is virtual machine (using VMware Workstation as host; the host CPU is mentioned in c1).
OK, this looks like a problem with the "-mno-rtm" CFlag: I tried to compile sys-devel/gcc-4.8.2 on various physical systems, for example - Intel(R) Xeon(R) CPU E5405 @ 2.00GHz - Intel(R) Xeon(R) CPU E31270 @ 3.40GHz - Intel(R) Core(TM) i7-2600 CPU - Intel(R) Core(TM) i7-3770K CPU - AMD Opteron(TM) Processor 6272 - AMD Opteron(tm) Processor 6164 HE On each system, # echo "" | gcc -march=native -v -E - 2>&1 | grep cc1 reports that GCC would activate "-mno-rtm", that's why I set this flag (have I misunderstand the command?). But with this flag set, sys-devel/gcc-4.8.2 won't build on these systems. It will fail with the quoted error. When I don't set the "-mno-rtm" flag, everything works fine...
libitm is a transactional memory library. -mno-rtm disables transactional memory instructions. So I can see how that would cause a build failure. -mrtm is added when libitm is built but your -mno-rtm is overriding it. We'll have to do something about that.
Fixed.
