[GSoC] Automatic Parallel Compilation Viability -- Final Report

Hi, This is the final report of the "Automatic Parallel Compilation Viability" project. Please notice that this report is pretty similar to the delivered from the 2nd evaluation, as this phase consisted of mostly rebasing and bug fixing. Please, reply this message for any question or suggestion.

Writing automated tests for the GCC driver

Hi, all. GCC have a extensive testsuite, that is no news at all. However they are focused on the compiler (cc1*) or in libraries, and I can't find tests related to the GCC driver. Are there tests to the GCC driver? If yes, is there any docs about how to write them? Thank you, Giuliano.

Help implementing support for vec in gengtype

Hi, all. I am tying to fix an issue with a global variable in the parallel gcc project. For this, I am trying to move some global variables from tree-ssa-operands to struct function. One of this variable is a vec type, and gengtype doesn't look so happy with it. In this context, I am trying to ad

Re: Parallelize the compilation using Threads

Hi, I was just wondering what API should I use to spawn threads and control its flow. Should I use OpenMP, pthreads, or something else? My point what if we break compatibility with something. If we use OpenMP, I'm afraid that we will break compatibility with compilers not supporting it. On the ot

Re: Parallelize the compilation using Threads

Hi, Since gimple-match.c takes so long to compile, I was wondering if it might be possible to reorder the compilation so we can push its compilation early in the dependency graph. I've attached a graphic showing what I mean and the methodology into PR84402 (https://gcc.gnu.org/bugzilla/show_bug.c
