Subject: | [Tinycc-devel] Some fixes for x86_64 and general code to enable compiling GCC |

Hi,I was bored the last weekend and stumbled over tinycc, tried compiling GCC with it, which breaks in multiple ways, sometimes not parsing stuff, sometimes miscompiling it, and thought about hacking some other compiler than GCC :) I just pushed nine patches to mob to fix all the problems I encountered (also attached for reference).
I've added testcases for all the issues to tcctest.c.I can now build current GCC (well, r186469 plus a modification, see below) with tinycc on x86_64 (all language frontends written in C, i.e. c, c++, objc, objc++ and fortran), and that so built GCC is able to compile all its own target libraries.
The nice thing is that I even found a real bug in GCC (fixing it is required to make it work with tinycc on x86_64), which I'm going to apply upstream later, but for completeness I attach it here too in case anyone wants to play with it right now (fix-diag-vaend.diff) :)
Have fun, Michael.
