The standard Chromium build system was modified to add -flto -Os to cflags (which I'm assuming in this case also gets passed to clang++) and -flto to ldflags in chromium/src/build/common.gypi and I think some of the build files for libraries that are built along with Chromium were modified to not use -flto because they didn't work. I'm not the one who did that work, unfortunately, so I can't say for sure exactly what all was modified. -- Stephen Checkoway

...tegrated-as -c -xc - Not implemented yet <stack dump> 3) There are -Wa options that the integrated assembler does not recognize. To reproduce these issues, try building chromium targeting Android with "clang=1" after adding '-integrated-as' to cflags in "build/common.gypi". http://code.google.com/p/chromium/wiki/Clang -Greg On Tue, Feb 5, 2013 at 6:27 AM, Renato Golin <renato.golin at linaro.org>wrote: > Hi all, > > I remember the discussion about promoting the integrated ARM assembler as > the default option, but I don't remember...

Hi all, I remember the discussion about promoting the integrated ARM assembler as the default option, but I don't remember the outcome. While compiling on ARM, I noticed that clang is not setting the integrated-as by default and is calling GAS before LD, which sometimes cause confusion (GAS doesn't like using r13 as a GPR, for instance). While this is unpredictable in Thumb, it's
