Hi Guys ,
We enabled the LTO on our code base and found that LTO uses the
integrated/builtin assembler to emit the final optimized code .O
(FileType= CGFT_ObjectFile) .
Can we bypass this semantic ,for something like you emit .S file
Then we pass this .S file to our native assembler and the linker
.....any switch/ options do so ?
i.e something like as we have "-no-integrated-as" for clang driver .
Currently ,we thought of hacking the LTOCodeGenerator.cpp for the same .
The bottom-line is that ,we need to use our native assembler ,not the builtin .
Any thoughts on this ?
We are trying on 3.6 and 3.8 versions.
