* Recognize Clang C and C++ compilers (see #10693)Brad King2010-05-171-0/+3
| | | | | | | Map to the platform and compiler information for GNU because the compilers are command-line compatible for common operations. Later we can add Clang-specific features as necessary. We honor the preferred capitalization is "Clang", not the common mis-spelling "CLang".

* Teach compiler id about VisualAge -> XL rebrandingBrad King2009-08-071-1/+7
| | | | | | | IBM rebranded its VisualAge compiler to XL starting at version 8.0. We use the compiler id "XL" for newer versions and "VisualAge" for older versions. We now also recognize the "z/OS" compiler, which is distinct from XL.
* ENH: Check _SGI_COMPILER_VERSION for compiler idBrad King2009-07-141-1/+1
| | | | | | Some SGI compilers define _SGI_COMPILER_VERSION in addition to the old _COMPILER_VERSION preprocessor symbol. It is more distinctive, so we should check it in case the old one is ever removed.
* ENH: Improve robustness of compiler INFO stringsBrad King2008-08-071-6/+15
| | | | | | | | | | | Compiler INFO strings built at preprocessing time encode information that must appear as a string literal in the resulting binary. We must make sure the strings appear in the final binary no matter what compiler and flags are used. The previous implementation worked in most places but failed with the GNU linker's --gc-sections option which managed to discard the string. Instead we make the program return value depend on an element of the string indexed by a runtime program parameter, which absolutely requires the string to be present.
* ENH: Make compiler id detection more robustBrad King2008-03-101-1/+5
| | | | | | | | | | - Split INFO strings in source into multiple pieces to make sure assembly or other listings produced by the compiler are never matched by the regex - Store INFO strings via pointer instead of array to convince some compilers to store the string literally in the binary - This should help make it work for sdcc 2.8.0 RC1
* ENH: Add support to C compiler identification for void return type from ↵Brad King2008-02-251-0/+7
| | | | main. Cross-compilers for embedded platforms may require it.
* ENH: Improvied compiler identification robustnessBrad King2008-02-251-0/+73
- Write a single source file into the compiler id directory - This avoid requiring the compiler to behave correctly with respect to include rules and the current working directory - Helps to identify cross-compiling toolchains with unusual default behavior
