            Bug ID: 111892
           Summary: [SH] [13 Regression] internal compiler error: Illegal
                    instruction when building e2fsprogs
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: glaubitz at physik dot fu-berlin.de
                CC: olegendo at gcc dot gnu.org, ysato at users dot sourceforge.jp
  Target Milestone: ---
            Target: sh-*-*-*

Created attachment 56156
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56156&action=edit
Preprocessed source from building rw_bitmaps.c with gcc-13

Since gcc-13, there is a regression in the SH backend which results in an
internal compiler error with the error message "Illegal instruction":

root@tirpitz:..lib/ext2fs> gcc-13 -I. -I../../lib -I../../../../lib -Wdate-time
-D_FORTIFY_SOURCE=2  -g -O2 -ffile-prefix-map=$(pwd)=.

gcc-12 works fine:

Is that on a native sh system or are you cross-compiling?  From which host?
Do you build GCC with --disable-checking by chance?

Can you provide a backtrace?

(In reply to Richard Biener from comment #2)
> Is that on a native sh system or are you cross-compiling?  From which host?

Yes, building on a native system (SH7785LCR) running Debian unstable on kernel
6.5.0. Host is sh4-linux-gnu.

> Do you build GCC with --disable-checking by chance?

No, it's built with "--enable-checking=release", see:

> https://buildd.debian.org/status/fetch.php?pkg=gcc-13&arch=sh4&ver=13.2.0-2&stamp=1691861588&raw=0

It's Debian's distribution gcc.

> Can you provide a backtrace?

So, just run the above gcc command inside gdb and print the backtrace?

This seems to be a dup of PR 111001.

Compiling the pre processed source with GCC-13 sh-elf cross compiler with 

sh-elf-gcc -m4 -Wdate-time -D_FORTIFY_SOURCE=2  -g -O2 -fPIE
-fstack-protector-strong -Wformat -Werror=format-security  -DHAVE_CONFIG_H -c
-dp -fdump-rtl-all -fdump-rtl-all-details rw_bitmaps.i

shows that the sh_treg_combine2 pass is hitting an infinite loop.

Adrian, can you please give it another go with the patch I've posted in PR

I'll rebuild gcc-13 with the patch now and report back. Could take 1-2 days.

I can confirm that this patch fixes the e2fsprogs build for me.

Also, marking this as duplicate of PR111001.
