Subject: [PATCH 137/188] LoongArch: When checking whether the assembler
|
||
|
|
supports conditional branch relaxation, add compilation parameter
|
||
|
|
"--fatal-warnings" to the assembler.
|
||
|
|
|
||
|
|
In binutils 2.40 and earlier versions, only a warning will be reported
|
||
|
|
when a relocation immediate value is out of bounds. As a result,
|
||
|
|
the value of the macro HAVE_AS_COND_BRANCH_RELAXATION will also be
|
||
|
|
defined as 1 when the assembler does not support conditional branch
|
||
|
|
relaxation. Therefore, add the compilation option "--fatal-warnings"
|
||
|
|
to avoid this problem.
|
||
|
|
|
||
|
|
gcc/ChangeLog:
|
||
|
|
|
||
|
|
* configure: Regenerate.
|
||
|
|
* configure.ac: Add parameter "--fatal-warnings" to assemble
|
||
|
|
when checking whether the assemble support conditional branch
|
||
|
|
relaxation.
