<pre>FreeBSD has several cases in its MIPS tree where .cpsetup is used with an
absolute offset instead of a label.
The most obvious use is in the gcc config for mips:
gcc/config/mips/mips.h
#if (defined _ABIN32 && _MIPS_SIM == _ABIN32) \
|| (defined _ABI64 && _MIPS_SIM == _ABI64)
#define CRT_CALL_STATIC_FUNCTION(SECTION_OP, FUNC) \
asm (SECTION_OP "\n\
.set noreorder\n\
bal 1f\n\
nop\n\
1: .set reorder\n\
.cpsetup $31, $2, 1b\n\
jal " USER_LABEL_PREFIX #FUNC "\n\
" TEXT_SECTION_ASM_OP);
#endif
I'm also tracking this in a freebsd bug at:
<a href="https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197259">https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197259</a></pre>
