Hii Everyone, I had already expressed my interest in the " Bypass assembler when generating LTO object files" project and making a proposal for the same. I know I should have done it earlier but I was admitted to the hospital for past few days :(. I have a few doubts. 1) "One problem is that the object files produced by libiberty/simple-object.c (which is the low-level API used by the LTO code) are missing some information (such as the architecture info and symbol table) and API of the simple object will need to be extended to handle that" I found this in the previous mailing list discussion. So who output this information currently in the object file, is it assembler? Also in the current patch for this project by Jan Hubica, from where are we getting these information from? Is it from crtbegin.o? 2) "Support in driver to properly execute *1 binary." I found this on Jan original patch's email. what does it mean exactly? Regards Rishi Raj
