The - options below facilitate fine grained control over what is and what - isn't made inline. For instance it can control things down to a - specific modules static routines. Doing this allows the compiler - to both eliminate the overhead of function calls and (as a - consequence) also eliminate further dead code. - - On a CISC (x86) I've found that I can achieve an order of magintude - speed improvement (x3-x5). In the case of RISC (sparc) while the - performance gain isn't as great it is still significant. - - Each module is controled by the macro <module>_INLINE which can - have the values described below - - 0 Do not inline any thing for the given module - - The following additional values are `bit fields' and can be - combined. - - REVEAL_MODULE: - - Include the C file for the module into the file being compiled - but do not make the functions within the module inline. - - While of no apparent benefit, this makes it possible for the - included module, when compiled to inline its calls to what - would otherwize be external functions. - - INLINE_MODULE: - - Make external functions within the module `inline'. Thus if - the module is included into a file being compiled, calls to - its funtions can be eliminated. 2 implies 1. - - INLINE_LOCALS: - - Make internal (static) functions within the module `inline'. - - In addition to this, modules have been put into two categories. - - INCLUDED_BY_MODULE - - eg sim-endian.h sim-bits.h - - Because these modules are small and simple and do not have - any complex interdendencies they are configured, if - <module>_INLINE is so enabled, to inline themselves in all - modules that include those files. - - For the default build, this is a real win as all byte - conversion and bit manipulation functions are inlined. - - !INCLUDED_BY_MODULE - - Complex modules - the rest - - These are all handled using the files sim-inline.h and - sim-inline.c. The main simulator engine includes both of - these and hence includes all remaining code. - - The following abreviations are available: - - INCLUDE_MODULE == (REVEAL_MODULE | INLINE_MODULE) - - ALL_INLINE == (REVEAL_MODULE | INLINE_MODULE | INLINE_LOCALS) - - ALL_BY_MODULE = (INCLUDED_BY_MODULE | ALL_INLINE) - - IMPLEMENTATION: - - The inline ability is enabled by prefixing every data / function - declaration and definition with one of the following: - - - INLINE_<module> - - Prefix to any global function that is a candidate for being - inline. - - values - `', `static', `static INLINE' - - - EXTERN_<module> - - Prefix to any global data structures for the module. Global - functions that are not to be inlined shall also be prefixed - with this. - - values - `', `static', `static' - - - STATIC_INLINE_<module> - - Prefix to any local (static) function that is a candidate for - being made inline. - - values - `static', `static INLINE' - - - static - - Prefix all local data structures. Local functions that are not - to be inlined shall also be prefixed with this. - - values - `static', `static' - - nb: will not work for modules that are being inlined for every - use (white lie). - - - extern - #ifndef _SIM_INLINE_C_ - #endif - - Prefix to any declaration of a global object (function or - variable) that should not be inlined and should have only one - definition. The #ifndef wrapper goes around the definition - propper to ensure that only one copy is generated. - - nb: this will not work when a module is being inlined for every - use. - - - STATIC_<module> - - Replaced by either `static' or `EXTERN_MODULE'. - - - REALITY CHECK: - - This is not for the faint hearted. I've seen GCC get up to 500mb - trying to compile what this can create. - - Some of the modules do not yet implement the WITH_INLINE_STATIC - option. Instead they use the macro STATIC_INLINE to control their - local function. - - Because of the way that GCC parses __attribute__(), the macro's - need to be adjacent to the functioin name rather then at the start -
