Subject: [PATCH 008/188] LoongArch: Delete macro definition
|
|
ASM_OUTPUT_ALIGN_WITH_NOP.
|
|
|
|
There are two reasons for removing this macro definition:
|
|
1. The default in the assembler is to use the nop instruction for filling.
|
|
2. For assembly directives: .align [abs-expr[, abs-expr[, abs-expr]]]
|
|
The third expression it is the maximum number of bytes that should be
|
|
skipped by this alignment directive.
|
|
Therefore, it will affect the display of the specified alignment rules
|
|
and affect the operating efficiency.
|
|
|
|
This modification relies on binutils commit 1fb3cdd87ec61715a5684925fb6d6a6cf53bb97c.
|
|
(Since the assembler will add nop based on the .align information when doing relax,
|
|
it will cause the conditional branch to go out of bounds during the assembly process.
|
|
This submission of binutils solves this problem.)
