Package: gcc-xtensa-lx106 Version: 12 Severity: normal X-Debbugs-Cc: vagr...@debian.org, reproducible-b...@lists.alioth.debian.org, kei...@keithp.com User: reproducible-bui...@lists.alioth.debian.org Usertags: toolchain Control: affects -1 picolibc
The reproducibility of picolibc appears to have changed due to the update of gcc-xtensa-lx106 from 11 to 12. Downloading version 11 from snapshot.debian.org and building picolibc with gcc-xtensa-lx106 11 builds reproducibly for me. picolibc /usr/lib/xtensa-lx106-elf/lib/crt0-hosted.o embeds the build path: /tmp/reprotest.mpqGso/const_build_path/debian/build/xtensa-lx106-elf vs. /tmp/reprotest.mpqGso/build-experiment-1/debian/build/xtensa-lx106-elf And randomized temporary filenames: /tmp/cc54YRFF.s vs. /tmp/cc8NLW2i.s Other architecture targets that picolibc builds appear to be unaffected, though at least gcc-riscv64* is currently gcc 11 based, but the arm variants have been upgraded gcc 12. I will see if I can come up with a simpler and faster reproducer for this issue, as building picolibc takes some time (though disabling tests and other architecture targets helps a lot). I have not looked for other packages that use gcc-xtensa-lx106, but it would be interesting to note changes in reproducibility for other packages as well. Thanks for maintaining gcc-xtensa-lx106! live well, vagrant
