CONST_DOUBLE_FORMAT

#define CONST_DOUBLE_FORMAT   ""

rtl.def needs CONST_DOUBLE_FORMAT, but we don't care what
CONST_DOUBLE_FORMAT is because we're not going to be generating
anything for CONST_DOUBLE anyway.

			NAME,
			FORMAT,
			CLASS )   { #ENUM, NAME, FORMAT },

NUM_RTX_CODE

Function Documentation

accessor_from_format()

static const char * accessor_from_format ( int c )

static

Decode a format letter into the proper accessor function.   

References gcc_unreachable.

Referenced by gendef().

always_void_p()

static bool always_void_p ( int idx )

inlinestatic

Return true if CODE always has VOIDmode.   

References defs, rtx_definition::enumname, and ggc_alloc().

Referenced by gen_exp(), and genmacro().

excluded_rtx()

static int excluded_rtx ( int idx )

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 defs, rtx_definition::enumname, and ggc_alloc().

Referenced by genmacro().

find_formats()

static void find_formats ( void )

static

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

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

Referenced by main().

gendef()

static void gendef ( const char * format )

static

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

References accessor_from_format(), rtx_definition::format, ggc_alloc(), i, and type_from_format().

Referenced by genheader().

genheader()

static void genheader ( void )

static

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

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

Referenced by main().

genlegend()

static void genlegend ( void )

static

Generate the documentation header for files we write.   

References ggc_alloc().

Referenced by main().

genmacro()

static void genmacro ( int idx )

static

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

References always_void_p(), defs, rtx_definition::enumname, excluded_rtx(), rtx_definition::format, ggc_alloc(), i, and special_rtx().

Referenced by genheader().

main()

int main

(

void

)

This is the main program.   

References FATAL_EXIT_CODE, find_formats(), genheader(), genlegend(), ggc_alloc(), and SUCCESS_EXIT_CODE.

special_format()

static int special_format ( const char * fmt )

static

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

References ggc_alloc().

Referenced by find_formats(), and genheader().

special_rtx()

static int special_rtx ( int idx )

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.cc).   

References defs, rtx_definition::enumname, and ggc_alloc().

Referenced by genmacro().

type_from_format()

static const char * type_from_format ( int c )

static

Decode a format letter into a C type string.
