4 | Subject: [PATCH] Only allow e500 double in SPE_SIMD_REGNO_P registers. | ||
5 | |||
6 | rs6000_hard_regno_nregs_internal allows SPE vectors in single | ||
7 | registers satisfying SPE_SIMD_REGNO_P (i.e. register numbers 0 to | ||
8 | 31). However, the corresponding test for e500 double treats all | ||
9 | registers as being able to store a 64-bit value, rather than just | ||
10 | those GPRs. | ||
11 | |||
12 | Logically this inconsistency is wrong; in addition, it causes problems | ||
13 | unwinding from signal handlers. linux-unwind.h uses | ||
14 | ARG_POINTER_REGNUM as a place to store the return address from a | ||
15 | signal handler, but this logic in rs6000_hard_regno_nregs_internal | ||
16 | results in that being considered an 8-byte register, resulting in | ||
17 | assertion failures. | ||
18 | (<https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02625.html> first | ||
19 | needs to be applied for unwinding to work in general on e500.) This | ||
20 | patch makes rs6000_hard_regno_nregs_internal handle the e500 double | ||
21 | case consistently with SPE vectors. | ||
22 | |||
23 | Tested with no regressions with cross to powerpc-linux-gnuspe (given | ||
24 | the aforementioned patch applied). Failures of signal handling | ||
25 | unwinding tests such as gcc.dg/cleanup-{8,9,10,11}.c are fixed by this | ||
26 | patch. | ||
27 | |||
28 | * config/rs6000/rs6000.c (rs6000_hard_regno_nregs_internal): Do | ||
29 | not allow e500 double in registers not satisyfing | ||
30 | SPE_SIMD_REGNO_P. | ||
