2 quick things: dead link + potential fix

Hi there, A quick note to say, first, thank you for providing such a great site! I am in the middle of a writing project (topic: finding - and keeping - a job in the modern world) and discovered your site while researching. And, second, I wanted to let you know that I did find a link that’s no

Re: increasing testsuite-errors when optimizing for amdfam10/bdver2

Hi, looks like XOP/FAM4/FAM is responsible for the additional errors I see when running gcc-testsuite or glibc-testsuite. I've opened Bug 56866 as a starting point, so the subject is a little bit misleading: Bug 56866 - gcc 4.7.x/gcc-4.8.x with '-O3 -march=bdver2' misscompiles glibc-2.17/crypt/s

Re: LRA assign same hard register with live range overlapped pseduos

Hi, Vladimir Previous patch probably not completed. The new patch will record lra_reg_info[i].offset as the offset from eliminate register to the pseudo i and keep updating when the stack has been changed. Therefore, lra-assign could get the latest offset to identify the pseudo content is equal or
