Bug 1463035 - Remove MOZ_SIGNAL_TRAMPOLINE. r?darchons
|
|
|
|
For some reason, GNU as is not happy with the assembly generated after
|
|
bug 1238661 anymore on Debian armel.
|
|
|
|
OTOH, as mentioned in bug 1238661 comment 4, we actually don't need this
|
|
workaround anymore, so let's just kill it.

|
