[Bug c/92773] GCC compilation with big array / header is infinite
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92773 --- Comment #6 from Charles-Antoine Couret --- Ok with a friend we identified a bit more what is the issue. So in fact I built (manually): $ gcc -Wall sound/soc/codecs/tas5756m.i -o sound/soc/codecs/tas5756m.o In that case, no output and it does not stop. But with: $ gcc sound/soc/codecs/tas5756m.i It finished very quickly with some linker errors. And with: $ gcc -Wall sound/soc/codecs/tas5756m.i There are a lot of outputs (warning for each line of my big arrays). And the process is really slow, some minutes to display the first 1000 lines. It seems slower over the time (the beginning seems really faster than the end). I assume that's the issue that I got with Linux build system. >From my point of view there is a performance regression somewhere. I don't think this behaviour is normal.

[Bug c/92773] New: GCC compilation with big array / header is infinite
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92773 Bug ID: 92773 Summary: GCC compilation with big array / header is infinite Product: gcc Version: 9.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: renault at fedoraproject dot org Target Milestone: --- Created attachment 47408 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47408&action=edit module driver I'm working on a new Linux kernel module. I'm using Fedora 31 with GCC 9.2.1 This module has several big arrays generated by a external tool which should be included into the driver itself. I use C headers for that. Without those headers, the compilation works fine. But if I try to include them, the compilation takes a infinite amount of time with cc1 process which uses one CPU at 100%. I tried with GCC 5.3.1 (Fedora 22) and 5.3.0 (Yocto) and the build succeed. And I don't see any reason to have this behaviour on earlier GCC.
