Subject: [PATCH 050/123] LoongArch: gas: Don't define LoongArch .align
|
|
|
|
Gcc may generate "\t.align\t%d,54525952,4\n" before commit
|
|
b20c7ee066cb7d952fa193972e8bc6362c6e4063. To write 54525952 (NOP) to object
|
|
file, we call s_align_ptwo (-4). It result in alignment padding must be a
|
|
multiple of 4 if .align has second parameter.
|
|
|
|
Use default s_align_ptwo for .align.
