[Git][cmucl/cmucl][issue-355-solaris-x86-fp-trap-handler] Solaris/x86 needs its own with-float-traps macro
by Raymond Toy (＠rtoy) 07 Sep '24

Raymond Toy pushed to branch issue-355-solaris-x86-fp-trap-handler at cmucl / cmucl Commits: 5db3c51f by Raymond Toy at 2024-09-06T15:39:33-07:00 Solaris/x86 needs its own with-float-traps macro For Solaris/x86, `with-float-traps` needs to handle the x87 and sse2 mode bits separately. The previous version used the merged value returned by `vm:floating-point-modes`. If the original mode had, say, the overflow flag set, when the macro restored the modes, the overflow flag was also set for x87 and sse2. Later on this can cause an expected overflow because the x87 mode has overflow set along with the sse2 mode. This shows up in the SIGFPE handler. To fix this, we handle the x87 and sse2 mode bits separately. Hence, we don't spuriously add back the overflow bit for x87 which didn't have it previously set. - - - - - 1 changed file: - src/code/float-trap.lisp Changes: ===================================== src/code/float-trap.lisp ===================================== @@ -568,6 +568,7 @@ (alien:sap-alien scp (* unix:sigcontext)) (logandc2 sse2-modes trap-bit))))))) +#-(and solaris x86) (macrolet ((with-float-traps (name merge-traps docstring) ;; Define macros to enable or disable floating-point @@ -631,6 +632,71 @@ accrued exceptions are cleared at the start of the body to support their testing within, and restored on exit.")) +#+(and solaris x86) +(macrolet + ((with-float-traps (name merge-traps docstring) + ;; Define macros to enable or disable floating-point + ;; exceptions.

Currently the control word is in the low 16-bits and the status word is in the high 16 bits. The status word contains the flags to show if an exception has occurred. However, the SSE2 mscsr register has the exception flags in the low part of the register. For consistency, put the status word in the low 16-bits of the result to match more closely what SSE2 does. This simplifies debugging when looking at the the x87 and sse2 modes independently. - - - - - ab7cfc59 by Raymond Toy at 2024-09-03T06:21:12-07:00 Clean up indentation; add a few comments. - - - - - c0f457a2 by Raymond Toy at 2024-09-03T07:22:59-07:00 Oops.
