Bug ID: 78364
Summary: [ARM] Error: bit-field extends past end of register --
ubfx
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Target: arm
Since commit r242414, I've noticed that libgcc fails to build for ARM with
messages like:
/tmp/5778677_3.tmpdir/ccer8XTS.s: Assembler messages:
/tmp/5778677_3.tmpdir/ccer8XTS.s:33: Error: bit-field extends past end of
register -- `ubfx r0,r0,#25,#8'
make[2]: *** [_fractUSQQQ.o] Error 1
make[2]: Leaving directory
`/tmp/5778677_3.tmpdir/aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-linux-gnueabihf/gcc1/arm-none-linux-gnueabihf/lib
gcc'
make[1]: *** [all-target-libgcc] Error 2
This is --target arm-none-linux-gnueabihf --with-mode=arm --with-cpu=cortex-a9
--with-fpu=vfp but all other combinations I tried have similar issues.
As Kyrill said on IRC, it might be a problem similar to PR77822.
