            Bug ID: 111928
           Summary: Build broken for baremetal targets after
                    r14-4825-g6a6d3817afa02b
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libquadmath
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dimitar at gcc dot gnu.org
  Target Milestone: ---

Following configure error is observed for pru-unknown-elf, arm-none-eabi, and
probably other baremetal targets:


Checking multilib configuration for libquadmath...
mkdir -p -- pru/libquadmath
Configuring in pru/libquadmath
....
checking for cos in -lm... configure: error: Link tests are not allowed after
GCC_NO_EXECUTABLES.
make[1]: *** [Makefile:13877: configure-target-libquadmath] Error 1


Issue probably started with r14-4825-g6a6d3817afa02b

--- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> ---
I'm trying to reproduce this, (and could be making some mistake) but I seem to
see

checking dynamic linker characteristics... no
checking how to hardcode library paths into programs... immediate
checking for shl_load... configure: error: Link tests are not allowed after
GCC_NO_EXECUTABLES.
make[1]: *** [Makefile:13636: configure-target-libstdc++-v3] Error 1

at r14-4820-g11f50716eee812 (which is before the patches I applied at the
weekend)

What was the last revision that you know was working?

I confirm that build works fine with r14-4820-g11f50716eee812, no maintainer
mode, for pru and arm targets.

I'm using x86_64-pc-linux-gnu build and host machine.

thanks, please could you post your configure line?

--- Comment #4 from Dimitar Dimitrov <dimitar at gcc dot gnu.org> ---
If I remove the "AC_CHECK_LIBM" line from libquadmath/configure.ac, and
re-generate autoconf there, then the build passes.

I don't understand why that line was added. Just a few lines below I see checks
for specific functions from libm.

That was what I was expecting - that line should not be there (it is a rebase
glitch that did not get picked up in either reviews or testing)

I am just trying to reproduce the problem and that fix..
