And _of course_ I forgot to attach the file.

Bug#972665: ICE building firefox-esr/firefox in unstable on armhf
Package: gcc-10 Version: 10.2.0-15 Severity: serious See the full buildd log in https://buildd.debian.org/status/fetch.php?pkg=firefox-esr&arch=armhf&ver=78.4.0esr-2&stamp=1603260510&raw=0 The preprocessed source that fails is attached as intrapred_neon.i.gz. This is reproducible on armhf with: gcc -o intrapred_neon.o -c -O1 -mfpu=neon intrapred_neon.i The shortened ICE message looks like: during RTL pass: reload /home/glandium/firefox-esr-78.4.0esr/third_party/aom/aom_dsp/arm/intrapred_neon.c: In function 'aom_highbd_dc_predictor_4x4_neon': /home/glandium/firefox-esr-78.4.0esr/third_party/aom/aom_dsp/arm/intrapred_neon.c:589:188: internal compiler error: in decompose_automod_address, at rtlanal.c:6298 589 | intra_pred_square(dc); | ^ 0x6cda45 decompose_automod_address ../../src/gcc/rtlanal.c:6298 0x6cda45 decompose_address(address_info*, rtx_def**, machine_mode, unsigned char, rtx_code) ../../src/gcc/rtlanal.c:6463 0x6cdb19 decompose_mem_address(address_info*, rtx_def*) ../../src/gcc/rtlanal.c:6486 0x59a67b process_address_1 ../../src/gcc/lra-constraints.c:3374 0x59c4cd process_address ../../src/gcc/lra-constraints.c:3648 0x59c4cd curr_insn_transform ../../src/gcc/lra-constraints.c:3963 0x5a088f lra_constraints(bool) ../../src/gcc/lra-constraints.c:5036 0x58e7a5 lra(_IO_FILE*) ../../src/gcc/lra.c:2443 0x54f331 do_reload ../../src/gcc/ira.c:5527 0x54f331 execute ../../src/gcc/ira.c:5713 Please submit a full bug report, with preprocessed source if appropriate. Please include the complete backtrace with any bug report. See for instructions. The code in question hasn't changed in a long time, so the same code effectively built fine with older versions of gcc. The last successful builds of firefox-esr and firefox were using gcc-10_10.2.0-9. I see in the gcc-10 changelog there is "On armel, armhf, configure with --enable-checking=yes,extra,rtl", this could be related. Mike
