- Subject: mips: -G0 vs __dso_handle
For mips-elf builds, crtbegin.o is built with -G 0 ("in case $gp isn't
used"). This makes __dso_handle be put in .data. However, the
"prototype" created by cp/decl.c is "void *__dso_data" which causes
GPrel addressing if your application is built without -G 0 (i.e. the
default), which causes link problems. This is causing numerous
testsuite failures like this example:
/dev/shm/ccvHNaHr.o: In function
`__static_initialization_and_destruction_0(int, int)':
omit-frame-pointer.C:(.text+0x58): relocation truncated to fit:
R_MIPS_GPREL16 against `__dso_handle'
Ideas?
