            Bug ID: 113635
           Summary: [14 Regression] libatomic has undefined reference to
                    libat_test_and_set_1_i2 in libatomic on
                    arm-linux-gnueabi
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org
  Target Milestone: ---

seen with trunk 20240127 (and earlier snapshots) on arm-linux-gnueabi,
configured with 

         --with-arch=armv5te
         --with-float=soft

This error is from a gcc-13 build, with the libatomic installed from a gcc-14
build, but also seen when enabling Ada or go in a trunk build:

/usr/bin/ld: /lib/arm-linux-gnueabi/libatomic.so.1: undefined reference to
`libat_test_and_set_1_i2'
collect2: error: ld returned 1 exit status
arm-linux-gnueabi-gnatlink-12: error when calling
/usr/bin/arm-linux-gnueabi-gcc-12
gnatmake: *** link failed.

The same thing also lets the build fail later in libgo.

$ objdump -T /usr/lib/arm-linux-gnueabi/libatomic.so.1|grep libat_
00000000      D  *UND*  00000000  Base        libat_test_and_set_1_i2

the libatomic from a GCC 13 build doesn't show this undefined symbol.
