| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2460 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Clean-up pass on C types:Gravatar xleroy2014-04-23
| | | | | | | | | | | | | - Ctypes: add useful functions on attributes; remove attrs in typeconv (because attributes are meaningless on r-values) - C2C: fixed missing or redundant Evalof - Cop: ignore attributes in ptr + int and ptr - int (meaningless on r-values); add sanity check between typeconv/classify_binarith and the C99 standard. - cparser: fixed several cases where incorrect type annotations were put on expressions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2457 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Merge of branch linear-typing:Gravatar xleroy2014-04-06
| | | | | | | | | | | | | | | | | | | | | | | 1) Revised division of labor between RTLtyping and Lineartyping: - RTLtyping no longer keeps track of single-precision floats, switches from subtype-based inference to unification-based inference. - Unityping: new library for unification-based inference. - Locations: don't normalize at assignment in a stack slot - Allocation, Allocproof: simplify accordingly. - Lineartyping: add inference of locations that contain a single-precision float. - Stackingproof: adapted accordingly. This addresses a defect report whereas RTLtyping was rejecting code that used a RTL pseudoreg to hold both double- and single-precision floats (see test/regression/singlefloats.c). This corresponds to commits 2435+2436 plus improvements in Lineartyping. 2) Add -dtimings option to measure compilation times. Moved call to C parser from Elab to Parse, to make it easier to measure parsing time independently of elaboration time. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2449 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* __builtin_absfloat can be applied to integers too.Gravatar xleroy2014-03-29
| | | | | | | | More precise classification of float results of arithmetic operations, in preparation for future work on the C/Clight static type system. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2441 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Inlining: preserve all RTL regs mentioned in the function, not justGravatar xleroy2014-03-29
| | | | | | | | those defined in the function. Semantically, both are correct, but the latter may cause RTLtyping to fail if some regs are uninitialized and a collision occurs between regs of different types. RTL: move the function resource computations there, as it could be useful for other passes some day. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2440 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
