Build busybox on mips with -g -O, there is a ice failure:
...
shell/ash.c:8758:1: internal compiler error: in dwarf2out_var_location, at dwarf2out.c:21264
...
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
{standard input}: Assembler messages:
{standard input}: Warning: missing .end at end of assembly
{standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive
...
The following line caused the ice failure on mips:
...
void evaltreenr(union node *, int) __attribute__ ((alias("evaltree"),__noreturn__));
...
So remove evaltreenr which was a alias of evaltree, and use evaltree
to instead.
