            Bug ID: 99723
           Summary: arm: ICE in build_function_type during selftests
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acoplan at gcc dot gnu.org
  Target Milestone: ---

If I configure a cross arm GCC with:

--enable-languages=c,c++ --disable-bootstrap --target=arm-linux-gnueabihf
--with-arch=armv8-a --with-float=hard

and run `make all-gcc`, the selftests fail with:

$ gcc/xgcc -B gcc -xc /dev/null -S -o /dev/null
-fself-test=/home/alecop01/toolchain/src/gcc/gcc/testsuite/selftests
cc1: error: ‘-mfloat-abi=hard’: selected processor lacks an FPU

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

If I add -march=armv8-a+simd to enable floating point, the selftests pass:
$ gcc/xgcc -B gcc -xc /dev/null -S -o /dev/null
-fself-test=/home/alecop01/toolchain/src/gcc/gcc/testsuite/selftests
-march=armv8-a+simd
-fself-test: 57120 pass(es) in 0.270736 seconds

At a minimum we probably shouldn't ICE here.

@richi: this is an arm (as in AArch32) bug, not aarch64.

    Don't ICE running selftests if errors were raised [PR99723]

    Hi all

    this is to address PR 99723.

    In the PR GCC crashes as the initialization of common trees is not
    performed as no compilation is happening, this is because we raise an
    error earlier while processing the arch flags.

    This patch changes the code to execute selftests only if no errors
    where raised before.

    Bootstrapped on aarch64, okay for trunk?

    Best Regards

      Andrea
