Package: qt4-x11
Version: 4.0.1-2
Tags: patch
qt4-x11 currently FTBFS for mips/mipsel because the assembler code for
atomic operations attempts to use MIPS II ll/sc instructions in MIPS I
assembly. The appended patch switches the atomic loops to assume MIPS II,
this works even for MIPS I CPUs because Linux emulates the ll/sc
instructions there.
