[cfe-commits] [PATCH] Oz optimization level sets ForceSizeOpt attribute for each function

[Quentin Colombet]

Hello,

Following the adding of the new ForceSizeOpt attribute in LLVM (see commit r1664220), I am making a patch for clang to set this attribute on each function when the Oz optimization level is set.

The idea is that optimizations will be able to adapt their behavior according to this attribute. In a second step, not given in this patch, it would be possible to make this attribute available for the end user, thus enabling code size optimization focus for specific functions.
The patch also contains a test case that check that the attribute is set when compiled in Oz and not set otherwise.
