- Subject: powerpc .lcomm oddity
This patch makes the powerpc .lcomm use the same subsection as the
generic .lcomm. I'm not sure why, but read.c:bss_alloc uses
subsection 1, possibly as a hack to avoid a problem seen on powerpc
with the following.
.section .bss,"aw",@nobits
.word 0
.lcomm test,1,1
One of these days when I have a little bit of spare time, I might even
fix this properly.
* config/tc-ppc.c (ppc_elf_lcomm): Use subsection 1.
