Bug ID: 99939
Summary: CMSE: -march=armv8.1-m.main+mve does not support
correctly.
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal

Pre-processor output file
The current arm-none-eabi-gcc does not support CMSE correctly on passing
command line option "-march=armv8.1-m.main+mve -mfloat-abi=hard -mfpu=auto
-mcmse".
On compiling the attached testcase test.c with mentioned command line I see
following error message:
$ arm-none-eabi-gcc -march=armv8.1-m.main+mve -mcmse -mfpu=auto
-mfloat-abi=hard -Wl,-section-start=.gnu.sgstubs=0x190000 --specs=rdimon.specs
test.i

/tmp/cc8Jg0A2.o: in function `secure_fun':
test.i:(.text+0x16): undefined reference to `cmse_check_address_range'
collect2: error: ld returned 1 exit status
I see "undefined reference to `cmse_check_address_range'" in the error message
but this function is present in the file gcc/libgcc/config/arm/cmse.c and is
available for multilib build with `-mcmse` option.
$ arm-none-eabi-gcc -v
Using built-in specs.
