| | | | | | | IA32: add __builtin_clz, __builtin_ctz. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2619 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Support C99 compound literals (by expansion in Unblock pass).Gravatar xleroy2014-08-21

* - Support "switch" statements over 64-bit integersGravatar xleroy2014-08-17
| | | | | | | | | | | | | (in CompCert C to Cminor, included) - Translation of "switch" to decision trees or jumptables made generic over the sizes of integers and moved to the Cminor->CminorSel pass instead of CminorSel->RTL as before. - CminorSel: add "exitexpr" to support the above. - ValueDomain: more precise analysis of comparisons against an integer literal. E.g. "x >=u 0" is always true. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2565 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* - Back to origins: suppress Mfloat64al32 chunk and align Mfloat64 to 4.Gravatar xleroy2014-01-12
| | | | | | | - Revised printing of intermediate RTL code. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2403 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* More tolerance for functions declared without a prototypeGravatar xleroy2013-12-28
| | | | | | | | (option -funprototyped, on by default). Error if call to vararg function and -fvararg-calls is off. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2389 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Simpler, more robust emulation of calls to variadic functions:Gravatar xleroy2013-12-28
| | | | | | | | | | | | | | - C function types and Cminor signatures annotated by calling conventions. esp. vararg / not vararg - Cshmgen: generate correct code for function call where there are more arguments than listed in the function prototype. This is still undefined behavior according to the formal semantics, but correct code is generated. - C2C, */PrintAsm.ml: remove "printf$iif" hack. - powerpc/, checklink/: don't generate stubs for variadic functions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2386 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* - Recognize __builtin_fabs as an operator, not just a builtin,Gravatar xleroy2013-11-06
| | | | | | | | | enabling more aggressive optimizations. - Less aggressive CSE for EF_builtin builtins, causes problems for __builtin_write{16,32}_reversed. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2363 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Floats.v, Nan.v: hard-wire the general shape of binop_pl, so that no axioms Gravatar xleroy2013-09-14
| | | | | | | | | are necessary, only two parameters (default_pl and choose_binop_pl). SelectDiv: optimize FP division by a power of 2. ConstpropOp: optimize 2.0 * x and x * 2.0 into x + x. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2326 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Treat casts int64 -> float32 as primitive operations instead of twoGravatar xleroy2013-07-03
| | | | | | | | casts int64 -> float64 -> float32. The latter causes double rounding errors. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2290 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Partial backtracking on previous commit: the "hole in Mach stack frame" Gravatar xleroy2013-03-03
| | | | | | | | trick prevents a future mapping of the Mach/Asm call stack as a single block. IA32 is fixed, PowerPC and ARM remains to be done. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2136 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Revised Stacking and Asmgen passes and Mach semantics: Gravatar xleroy2013-03-01
| | | | | | | | | | - no more prediction of return addresses (Asmgenretaddr is gone) - instead, punch a hole for the retaddr in Mach stack frame and fill this hole with the return address in the Asmgen proof. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2129 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
