This breaks my MIPS build:
common/libcommon.a(exports.o)(.text+0xdc): In function `jumptable_init':
/home/skuribay/bootloader/u-boot/u-boot.git/common/exports.c:32: undefined reference to `strcmp'
make: *** [u-boot] Error 1
We MIPS have arch-specific strcmp defined in <asm/string.h>.
Since strcmp is inlined, we couldn't refer them by function pointer.
The nm of lib_generic/string.o is like this:
U _gp_disp
U malloc
00000610 T memchr
00000520 T memcmp
00000474 T memcpy
000004a4 T memmove
00000448 T memset
00000000 T strcat
00000084 T strchr
00000198 T strdup
000000c0 T strlen
00000038 T strncat
0000015c T strnlen
00000270 T strpbrk
000000e4 T strrchr
00000380 T strsep
00000210 T strspn
00000550 T strstr
000003ec T strswab
000002c0 T strtok
00000004 C ___strtok
I think all architectures which have __HAVE_ARCH_STRCMP defined will
encounter this error. What is the proper workaround?
Thanks,
Shinya Kuribayashi
