Hi,
|
|
|
7b26da |
|
|
|
7b26da |
I have somehow missed gdb.asm/asm-source.exp PASS->FAIL even on x86_64.
|
|
|
7b26da |
|
|
|
7b26da |
It has no longer valid assumption that "break" breaks after the prologue even
|
|
|
7b26da |
in assembler. So I have changed this assumption of the testfile.
|
|
|
7b26da |
|
|
|
7b26da |
Tested it FAIL->PASSes on x86_64, ppc64 and s390x.
|
|
|
7b26da |
|
|
|
7b26da |
OK for check-in?
