Bug ID: 102842 Summary: [10 Regression] ICE in cselib_record_set at 02 or greater Product: gcc Version: 10.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: herrtimson at yahoo dot de Target Milestone: --- Created attachment 51634 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51634&action=edit compressed build log I'm hitting this when compiling firefox nightly with --enable-jxl, using gcc-10.3.0 cross-compiler with amd64 host and armv7a target. Affected are -02 and -03, -01 is fine. It is unknown wether the error is cross compile specific, my rpi2 device doesn't have near enough ram to compile firefox with native gcc on it. Anyway, here is the error message: 23:39.63 | ^~~~~~ 23:41.47 during RTL pass: postreload 23:41.47 /usr/armv7a-unknown-linux-gnueabihf/tmp/portage/www-client/firefox-95.0/work/firefox-95.0/third_party/jpeg-xl/lib/jxl/dec_reconstruct.cc: In function 'jxl::Status jxl::FinalizeImageRect(jxl::Image3F*, const jxl::Rect&, const std::vector<std::pair<jxl::Plane<float>*, jxl::Rect> >&, jxl::PassesDecoderState*, size_t, jxl::ImageBundle*, const jxl::Rect&)': 23:41.47 /usr/armv7a-unknown-linux-gnueabihf/tmp/portage/www-client/firefox-95.0/work/firefox-95.0/third_party/jpeg-xl/lib/jxl/dec_reconstruct.cc:1080:1: internal compiler error: in cselib_record_set, at cselib.c:2614 23:41.47 1080 | } 23:41.47 | ^ 23:41.80 In file included from /usr/armv7a-unknown-linux-gnueabihf/tmp/portage/www-client/firefox-95.0/work/firefox_build/dist/include/nsTArray.h:3331, 23:41.80 from /usr/armv7a-unknown-linux-gnueabihf/tmp/portage/www-client/firefox-95.0/work/firefox-95.0/netwerk/cache2/CacheIOThread.h:11, 23:41.80 from /usr/armv7a-unknown-linux-gnueabihf/tmp/portage/www-client/firefox-95.0/work/firefox-95.0/netwerk/cache2/CacheFileIOManager.h:8, 23 the souce code in question can be accessed via this link: https://github.com/mozilla/gecko-dev/blob/master/third_party/jpeg-xl/lib/jxl/dec_reconstruct.cc#L1080
