Bug ID: 31676
Summary: Configuring with CC="gcc -march=x86-64-v3"
--with-rtld-early-cflags=-march=x86-64 results in
linker failure
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
The error is:

The reason is that we build with sysdeps/x86/dl-get-cpu-features.c with the
early CFLAGS (so -march=x86-64). This is necessary because the code runs very
early. But since

x86-64: Don't use SSE resolvers for ISA level 3 or above
When glibc is built with ISA level 3 or above enabled, SSE resolvers
aren't available and glibc fails to build:
ld: .../elf/librtld.os: in function `init_cpu_features':
.../elf/../sysdeps/x86/cpu-features.c:1200:(.text+0x1445f): undefined
reference to `_dl_runtime_resolve_fxsave'
ld: .../elf/librtld.os: relocation R_X86_64_PC32 against undefined hidden
symbol `_dl_runtime_resolve_fxsave' can not be used when making a shared object
/usr/local/bin/ld: final link failed: bad value
For ISA level 3 or above, don't use _dl_runtime_resolve_fxsave nor
_dl_tlsdesc_dynamic_fxsave.
This fixes BZ #31429.
Reviewed-by: Noah Goldstein <goldstein.w.n@gmail.com>
the referenced _dl_runtime_resolve_fxsave trampoline does not exist when the
rest of the dynamic linker is built for x86-64-v3.

Does such glibc binary require x86-64-v3 to run?

(In reply to H.J. Lu from comment #1)
> Does such glibc binary require x86-64-v3 to run?
Yes, but we really want ld.so be able to print an error message on all CPUs, as
in “Fatal glibc error: CPU does not support x86-64-v3". See
sysdeps/x86/dl-get-cpu-features.c. This requires that we build part of ld.so
with -march=x86-64.
