-Subject: [PATCH] Only allow e500 double in SPE_SIMD_REGNO_P registers.
-
-rs6000_hard_regno_nregs_internal allows SPE vectors in single
-registers satisfying SPE_SIMD_REGNO_P (i.e. register numbers 0 to
-31). However, the corresponding test for e500 double treats all
-registers as being able to store a 64-bit value, rather than just
-those GPRs.
-
-Logically this inconsistency is wrong; in addition, it causes problems
-unwinding from signal handlers. linux-unwind.h uses
-ARG_POINTER_REGNUM as a place to store the return address from a
-signal handler, but this logic in rs6000_hard_regno_nregs_internal
-results in that being considered an 8-byte register, resulting in
-assertion failures.
-(<https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02625.html> first
-needs to be applied for unwinding to work in general on e500.) This
-patch makes rs6000_hard_regno_nregs_internal handle the e500 double
-case consistently with SPE vectors.
-
-Tested with no regressions with cross to powerpc-linux-gnuspe (given
-the aforementioned patch applied). Failures of signal handling
-unwinding tests such as gcc.dg/cleanup-{8,9,10,11}.c are fixed by this
-patch.
-
- * config/rs6000/rs6000.c (rs6000_hard_regno_nregs_internal): Do
- not allow e500 double in registers not satisyfing
- SPE_SIMD_REGNO_P.
