Subject: [PATCH 3/5] Fix QtCore compilation with clang
|
|
|
|
The .altmacro is not supported with Clang's integrated assembly.
|
|
|
|
The worst part is that I had this fixed, but apparently I never pushed
|
|
the update to Gerrit and then we staged the old version. This commit
|
|
brings back the fixes.
|
|
|
|
Incidentally, it also makes things work with freebsd-clang.
