search for: all_symbols_read_hook

Hi, I found some posts on the topic of whole program bitcode and gold plugin. I put lto_codegen_write_merged_modules(cg, "/path/to/output.bc") into gold-plugin.cpp all_symbols_read_hook() and compiled one autotooled program (ftp://ftp.gnu.org/gnu/diction/diction-1.11.tar.gz) as described in the gold plugin document, however, I still did not see the output.bc. Can anyone has succeeded in doing this share with me how you archive this or what I may miss? Thanks very much, Guolia...

Nicholas? > I've had some success by adding a call to lto_codegen_write_merged_modules(cg, somePath) at the end of the gold plugin's all_symbols_read_hook() function just before it calls lto_codegen_dispose(cg). The somePath is set via a plugin option which I patched llvm-gcc to pass through as a derivation from its -o argument. It has worked on several mid-complexity applications I've tried so far (lighttpd, wu-ftpd, tcdump, and the sqlite lib...

In gold-plugin.cpp all_symbols_read_hook() where lto_codegen_compile(cg, ...) is currently called, call lto_codegen_write_merged_modules(cg, "/path/to/output.bc") instead. If someone were to rig this up to a command-line flag (search for LDPT_OPTION in the same file) then I would like to commit that change. Nick > The a...

Afaik gold does not help here. I tried it and managed to only generate native code. I'm currently investigating an alternative approach to produce whole-program bitcodes: 1) add
