https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261977 --- Comment #19 from Robert Clausecker <fuz@fuz.su> --- (In reply to Piotr Kubaj from comment #18) Built times are not super relevant as long as they stay in a reasonable range. Waiting 3 days for the compiler to build is not reasonable. And as I said, this is both for native and for cross builds from reasonably fast hardware. Whenever there is some sort of update to the ports tree that changes a dependency of gcc, Poudriere recompiles gcc. So excessive build times significantly interfere with my ability to test ports. Right now I do not change any build flags nor do I provide any custom options because if I did, my test results would not be applicable. And even for normal, source-building users (which do exist), waiting three days for a compiler to be built is completely unreasonable. And that's the time up until now. The compiler build has not finished yet and I don't know when it will. Have you weighed the extra build time against the performance advantage this brings? How much does the LTO-built gcc speed up build times in comparison to a normally built (or even non-bootstrapped) gcc? -- You are receiving this mail because: You are on the CC list for the bug.help
