            Bug ID: 101369
           Summary: Bootstrap failure of gcc-12-20210704 on Cygwin
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mckelvey at maskull dot com
  Target Milestone: ---

Created attachment 51114
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51114&action=edit
Tarball of build.log and config.log

Recent gcc-11 and gcc-12 snapshots fail with:

/bin/sh: build/genmodes.exe: cannot execute binary file: Exec format error

Using gcc version 11.1.1 20210619:

$ g++ -v
Using built-in specs.
COLLECT_GCC=g++
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-pc-cygwin/11.1.1/lto-wrapper.exe
Target: x86_64-pc-cygwin
Configured with: ./configure --enable-languages=c,c++ --enable-threads=posix
Thread model: posix
Supported LTO compression algorithms: zlib
gcc version 11.1.1 20210619 (GCC)

(Fails the same way on the gcc-10 provided in Cygwin.)

$ uname -r
3.2.0(0.340/5/3)

What binutils (as/ld) you are using?  Have you tried a newer version of
binutils?
This could be a binutils bug.

$ ld -v
GNU ld (GNU Binutils) 2.36.1

My Cygwin is up-to-date AFAIK.

IIRC there was a recently filed duplicate.

Probably duplicate of 101377 for 11.1.1. I see error for 11 and 12.

It is the same for both.
