Hi all, I have built GCC with BUILD_CONFIG="bootstrap-O1" with the intention of contributing, hence O1. I ran across two separate build errors, however. Online, I have found mentions of others running into similar errors on O1. I have made a local patch to fix both build errors and have since been able to successfully build GCC. I was wondering if I did something wrong, perhaps? Does no-one use O1 to build when working on GCC? What do contributors' build settings usually look like? If others did, surely this would have been noticed, no? Both errors are related to uninitialized variables. One at https://github.com/gcc-mirror/gcc/blob/master/gcc/config/i386/i386-options.cc#L3085 and one at https://github.com/gcc-mirror/gcc/blob/master/gcc/tree-tailcall.cc#L472 If welcome, I can submit my local patches for review. PS. What email client do you guys use to wrap your mails? I noticed it'd be a good idea to wrap my messages to about 80 characters. Thanks, Tuur Martens
