However, for x87, the float mode can be at least 26 bits long. This showed up running the unit test suite. Examining the bits in the control word shows that 26 is the max, if you ignore the reserved bits at the high part of the control word. For sse2, the mxcsr register only has 16 defined bits. Thus, split `float-modes` into separate types, one for x87 and one for sse2. - - - - - 1 changed file: - src/compiler/x86/float-sse2.lisp Changes: ===================================== src/compiler/x86/float-sse2.lisp ===================================== @@ -1265,7 +1265,8 @@ ;;;; Float mode hackery: -(deftype float-modes () '(unsigned-byte 24)) +(deftype x87-float-modes () '(unsigned-byte 32)) +(deftype sse2-float-modes () '(unsigned-byte 16)) ;; For the record, here is the format of the MXCSR register. ;; @@ -1288,8 +1289,8 @@ ;; 0 invalid operation flag ;; ;; See below for rounding control -(defknown sse2-floating-point-modes () float-modes (flushable)) -(defknown ((setf sse2-floating-point-modes)) (float-modes) float-modes) +(defknown sse2-floating-point-modes () sse2-float-modes (flushable)) +(defknown ((setf sse2-floating-point-modes)) (sse2-float-modes) sse2-float-modes) ;; Returns exactly the mxcsr register, except the masks are flipped ;; because we want exception enable flags, not masks. @@ -1375,9 +1376,9 @@ ;; 10 double precision (53 bits) ;; 11 double extended precision (64 bits) -(defknown x87-floating-point-modes () float-modes (flushable)) -(defknown ((setf x87-floating-point-modes)) (float-modes) - float-modes) +(defknown x87-floating-point-modes () x87-float-modes (flushable)) +(defknown ((setf x87-floating-point-modes)) (x87-float-modes) + x87-float-modes) ;; Extract the control and status words from the FPU.

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.
