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
cc1: internal compiler error: in build_function_type, at tree.c:8432

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.
