[llvm-dev] LLVM Pass in compiling and linking

[Muhui Jiang via llvm-dev]

Hi

According to the official documentation. It says to use the tool opt -load
to run LLVM pass on the target bitcode.

According to my observation. When the program is very large, it is very
slow and not efficient. I noticed that LLVM support to run LLVM pass during
the compiling time or linking time.

For compiling time. It seems that the option -Xclang -load -Xclang
mypass.so will work. However, after generating the object. the ld linker
will say that it has no option -load. Thus aborted.

What can I do? I just want to write a LLVM pass and run it during the
compiling time.  No documentation is found. Could anyone tell me or give me
some help? Many Thanks

Regards
Muhui
