Subject: [PATCH] powerpc: Fix strstr/power7 build
|
|
|
8ae002 |
|
|
|
8ae002 |
This patch fixes the strstr build with --disable-multi-arch option.
|
|
|
8ae002 |
The optimization calls the __strstr_ppc symbol, which always build
|
|
|
8ae002 |
for multiarch config but not if it is disable. This patch fixes it
|
|
|
8ae002 |
by adding the default C implementation object with the expected
|
|
|
8ae002 |
symbol name.
|
|
|

|
|
|
8ae002 |
* sysdeps/powerpc/powerpc64/power7/Makefile [$(subdir) = string]
|
|
|
8ae002 |
(sysdep_routines): Add strstr-ppc64.
|
|
|
8ae002 |
* sysdeps/powerpc/powerpc64/power7/strstr-ppc64.c: New file.
|
