Hi,
I'm trying to adjust an already existing target port of gcc-2.95.2 to
gcc-4.1.0 and I came to a point where I could use some help. Everything
seams fine until xgcc tries to compile libgcc2.c, then I get the following
error messages:
libgcc2.s: Assembler messages:
libgcc2.s:52: Error: unknown pseudo-op: `.lm_0'
libgcc2.s:61: Error: unknown pseudo-op: `.lm_1'
libgcc2.s:83: Error: unknown pseudo-op: `.lm_2'
libgcc2.s:89: Error: unknown pseudo-op: `.lm_3'

libgcc2.s:133: Error: unknown pseudo-op: `.lm_10'
libgcc2.s:139: Error: unknown pseudo-op: `.lm_11'
I have looked into the assembler file, and found out that those are
actually labels which are missing ":" at the end and that the labels are
redundant. Here is the part of the file:
.global ___muldi3
___muldi3:
.stabd 46,0,0
.stabd 68,0,511
.LM_0
.LM_0:
#BEGIN PROLOGUE
frame L14, L4
#END PROLOGUE
.LBB_2:
.LBB_3:
.stabd 68,0,514
.LM_1
.LM_1:
mov L8 , L1
mov L7 , L3
shri L8 , 16
I have found out that the correct labels are written out by the hook
TARGET_ASM_INTERNAL_LABEL and the faulty ones are the result of the output
from the macro ASM_GENERATE_INTERNAL_LABEL, but I cannot figure out why the
latter ones gets written out at all.
Best regards
Andrija
