(Fixes issue with wrong comparison of pointers across 0x8000_0000) - Revised Stacking pass to not use negative SP offsets. - Add pointer validity checks to Cminor ... Mach to support the use of memory injections in Stacking. - Cleaned up Stacklayout modules. - IA32: improved code generation for Mgetparam. - ARM: improved code generation for op-immediate instructions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1632 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- cfrontend/Cshmgen.v | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'cfrontend/Cshmgen.v') diff --git a/cfrontend/Cshmgen.v b/cfrontend/Cshmgen.v index 87dfc877..f1f7c0ac 100644 --- a/cfrontend/Cshmgen.v +++ b/cfrontend/Cshmgen.v @@ -199,8 +199,9 @@ Definition make_shr (e1: expr) (ty1: type) (e2: expr) (ty2: type) := Definition make_cmp (c: comparison) (e1: expr) (ty1: type) (e2: expr) (ty2: type) := match classify_cmp ty1 ty2 with - | cmp_case_iiu => OK (Ebinop (Ocmpu c) e1 e2) - | cmp_case_ipip => OK (Ebinop (Ocmp c) e1 e2) + | cmp_case_ii Signed => OK (Ebinop (Ocmp c) e1 e2) + | cmp_case_ii Unsigned => OK (Ebinop (Ocmpu c) e1 e2) + | cmp_case_pp => OK (Ebinop (Ocmpu c) e1 e2) | cmp_case_ff => OK (Ebinop (Ocmpf c) e1 e2) | cmp_case_if sg => OK (Ebinop (Ocmpf c) (make_floatofint e1 sg) e2) | cmp_case_fi sg => OK (Ebinop (Ocmpf c) e1 (make_floatofint e2 sg)) -- cgit
