Function Documentation

static const char* accessor_from_format ( )

static

Decode a format letter into the proper accessor function.   

Referenced by gendef().

static int excluded_rtx ( )

static

Return nonzero if the RTL code given by index IDX is one that we should
   generate no macro for at all (because gen_rtx_FOO is never used or
   cannot have the obvious interface).   

References rtx_definition::enumname.

Referenced by genmacro().

static void find_formats ( )

static

Place a list of all format specifiers we use into the array FORMAT.   

References rtx_definition::format, formats, NUM_RTX_CODE, and special_format().

Referenced by main().

static void gendef ( )

static

Generate the code for the function to generate RTL whose
   format is FORMAT.   

References accessor_from_format(), and type_from_format().

Referenced by genheader().

static void genheader ( )

static

Generate the text of the header file we make, genrtl.h.   

References rtx_definition::format, formats, gendef(), genmacro(), NUM_RTX_CODE, and special_format().

Referenced by main().

static void genlegend ( )

static

Generate the documentation header for files we write.   

Referenced by main().

static void genmacro ( )

static

Generate macros to generate RTL of code IDX using the functions we
   write.   

References rtx_definition::enumname, excluded_rtx(), rtx_definition::format, and special_rtx().

Referenced by genheader().

int main

(

)

This is the main program.   

References find_formats(), genheader(), and genlegend().

static int special_format ( )

static

Return nonzero if we should ignore FMT, an RTL format, when making
   the list of formats we write routines to create.   

Referenced by find_formats(), and genheader().

static int special_rtx ( )

static

Return nonzero if the RTL code given by index IDX is one that we should
   generate a gen_rtx_raw_FOO macro for, not gen_rtx_FOO (because gen_rtx_FOO
   is a wrapper in emit-rtl.c).   

References rtx_definition::enumname.

Referenced by genmacro().

static const char* type_from_format ( )

static

Decode a format letter into a C type string.   

Referenced by gendef().
