This support does not replace but comes in + addition to CompCert's original support for 32-bit target platforms, + with 32-bit pointers and emulation of 64-bit integer arithmetic + using pairs of 32-bit integers. In terms of C data models, CompCert + used to be restricted to the ILP32LL64 model; now it also supports + I32LP64 and IL32LLP64. + +- The x86 port of CompCert was extended to produce x86-64 bit code in + addition to the original x86-32 bit (IA32) code. (This is the first + instantiation of the new support for 64-bit targets described + above.) Support for x86-64 is currently available for Linux and MacOS X. + (Run the configure script with 'x86_64-linux' or 'x86_64-macosx'.) + + + Release 2.7.1, 2016-07-18 ========================= @@ -7,9 +29,9 @@ Bug fixing: - Fixed a compile-time assertion failure involving builtins taking a 64-bit integer parameter and given an unsigned 32-bit integer argument. -- Updates to the Cminor parser. +- Updates to the Cminor parser. + - Release 2.7, 2016-06-29 ======================= |
