Hi,
on hppa, powerpc and sh4, the build fails due to GCC running out of memory [1]:
FAILED: [code=1]
Source/WebCore/CMakeFiles/WebCore.dir/__/__/WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-40.cpp.o
/usr/bin/c++ -DBUILDING_GTK__=1 -DBUILDING_WEBKIT=1 -DBUILDING_WITH_CMAKE=1

/build/reproducible-path/webkit2gtk-2.50.4/build-soup3/WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-40.cpp
virtual memory exhausted: Cannot allocate memory
After reading through the ReduceBuildMemoryOverhead article [2] on the Debian
wiki,
I discovered the option "-no-integrated-cpp" which helps work around the OOM
issue
above. Together with the "--param ggc-min-expand=10" option, the build suceeds:

But since armhf and i386 don't run out of memory, I suggest to use the
workaorund on
hppa, m68k, powerpc and sh4. For sh4, an additional patch is required to
disable the
musttail attribute.
Thanks,
