• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Ilya Yesin 2019-05-21 21:46:55 UTC]

Tried to do emerge --update --newuse @world and got a bunch of messages like
```
error: inlining failed in call to always_inline '_xend': target specific option mismatch _xend (void)
```


Reproducible: Always

Steps to Reproduce:
1. have up to date gcc-8.3.0
2. Try to build sys-libs/glibc-2.29-r3

Actual Results:  
Compilation failed

Expected Results:  
Compilation and installation successful

I suggest not using -mno-* flags in CFLAGS/CXXFLAGS as usually there is no need for it. It negates explicit extensions enabled by glibc build system for arch-specific runtime optimisations, like -mhle.

Something like
    $ diff -U0 <(gcc -Q --help=target) <(gcc -Q --help=target -march=native)
should yield only necessary changes WRT default values.

See bug #581602.

Or in your case it would be
    $ diff -U0 <(gcc -Q --help=target -march=bdver2) <(gcc -Q --help=target -march=native)

[Comment 4 Ilya Yesin 2019-05-22 21:11:36 UTC]

Hello Sergei,

Thank you for quick reply!

> $ diff -U0 <(gcc -Q --help=target -march=bdver2) <(gcc -Q --help=target -march=native)

This command return no result (so, no difference).
Removing '-mno*' flags allowed build to finish.

One question on this topic: since there is no difference in output '-Q --help=target -march={bdver2,native}', would it be good idea to remove rest of '-m*' options from make.conf?

Yes
    CFLAGS="-march=bdver2 -mtune=bdver2 --param=l1-cache-size=... --param=l1-cache-line-size=... --param=l2-cache-size="
should have the same effect on your system (except avoiding accidental -mno-* effect).

[Comment 6 Ilya Yesin 2019-06-16 14:53:50 UTC]

Removing all -mno* from CFLAGS solved the issue.
