Created attachment 497420 [details] build.log Hello! Thanks for the pgo flag. However, if before gcc was going to lto (flag -flto in BOOT_CFLAGS, as described in the documentation for gcc), now it gives an error. The log is attached.
The failure is a gcc ICE: > lto1: internal compiler error: in lto_varpool_replace_node, at lto/lto-symtab.c:143 > Please submit a full bug report, with preprocessed source if appropriate. > See <https://bugs.gentoo.org/> for instructions. Do newer gcc version work for you?
Version in the repository has not changed - sys-devel/gcc-5.4.0-r3. Again I got an error when assembling: lto1: internal compiler error: in lto_varpool_replace_node, at lto/lto-symtab.c:143
(In reply to Vladimir Kolesnichenko from comment #2) > Version in the repository has not changed - sys-devel/gcc-5.4.0-r3. > Again I got an error when assembling: > lto1: internal compiler error: in lto_varpool_replace_node, at > lto/lto-symtab.c:143 My question was if you tried newer upstream gcc versions, namely =sys-devel/gcc-6.4.0 or =sys-devel/gcc-7.2.0
Version 6.4 in my build is indicated as "unstable". Version 7.2 is not available (Calculate linux). I can unmask version 6.4 and check in the evening on my home computer. To do this, please indicate which versions of which packages should also be unmasked.
I suggest checking =sys-devel/gcc-6.4.0 (USE='lto pgo' did not fail fo r me at build time).
Assuming 6.4.0 (stable on amd64) works fine.
