Functions

addtofixlist size_t addtofixlist(Symbol* s, targ_size_t offset, int seg, targ_size_t val, int flags): Add to the fix list.
cat code* cat(code* c1, code* c2): Concatenate two code lists together. Return pointer to result.
cgen_prelinnum
void cgen_prelinnum(code** pc, Srcpos srcpos): Prepend line number to existing code.
code_last code* code_last(code* c): Find last code in list.
code_orflag void code_orflag(code* c, uint flag): Set flag bits on last code in list.
code_orrex void code_orrex(code* c, uint rex): Set rex bits on last code in list.
gen code* gen(code* c, code* cs): Add code to end of linked list. Note that unused operands are garbage. gen1() and gen2() are shortcut routines. Input: c -> linked list that code is to be added to end of cs -> data for the code
genadjfpu code* genadjfpu(code* c, int offset): Generate 'instruction' which tells the scheduler that the fpu stack has changed.
genc code* genc(code* c, opcode_t op, uint ea, uint FL1, targ_size_t EV1, uint FL2, targ_size_t EV2): Generate code.
gencodelem void gencodelem(CodeBuilder cdb, elem* e, regm_t* pretregs, bool constflag): Clean stack after call to codelem().
genlinnum code* genlinnum(code* c, Srcpos srcpos): Generate 'instruction' which is actually a line number.
gennop code* gennop(code* c): Generate 'nop'
outfixlist void outfixlist(): End of module. Output fixups as references to external Symbols.
reghasvalue bool reghasvalue(regm_t regm, targ_size_t value, reg_t* preg): Determine if one of the registers in regm has value in it. If so, return !=0 and set *preg to which register it is.
regwithvalue void regwithvalue(CodeBuilder cdb, regm_t regm, targ_size_t value, reg_t* preg, regm_t flags): Load a register from the mask regm with value. Output: *preg the register selected

Structs

Fixup struct Fixup: When we don't know whether a function symbol is defined or not within this module, we stuff it in an array of references to be fixed up later.
