[GCC][PATCH][ARM] Add multilib mapping for Armv8.1-M+MVE with -mfloat-abi=hard
This patch adds a new multilib for armv8.1-m.main+mve with hard float abi. For
armv8.1-m.main+mve soft and softfp, the v8-M multilibs will be reused.
The following mappings are also updated:
"-mfloat-abi=hard -march=armv8.1-m.main+mve.fp -> armv8-m.main+fp/hard"
"-mfloat-abi=softfp -march=armv8.1-m.main+mve.fp -> armv8-m.main+fp/softfp"
"-mfloat-abi=soft -march=armv8.1-m.main+mve.fp -> armv8-m.main/nofp"
gcc/ChangeLog:
2020-03-17 Mihail Ionescu <mihail.ionescu@arm.com>
* config/arm/t-rmprofile: create new multilib for
armv8.1-m.main+mve hard float and reuse v8-m.main ones for
v8.1-m.main+mve .
gcc/testsuite/ChangeLog:
2020-03-17 Mihail Ionescu <mihail.ionescu@arm.com>
* gcc.target/arm/multilib.exp: Add new v8.1-M entry.
libgcc/ChangLog:
2020-03-17 Mihail Ionescu <mihail.ionescu@arm.com>
