### On m68k, gcc creates short assembler branch insns, and expects
|
|
### the assembler to adapt them to the distance. m68k gas appears not to
|
|
### do that for fpu branch insns, resulting in an out-of-range FPU
|
|
### assembler branch instruction error in "ext/re/re_exec.c".
|
|
###
|
|
### As a workaround, building with "-Os" instead of "-O2" reduces
|
|
### the size of the object file enough to allow short branches.
|

### See PR toolchain/45439.
