static Instruction *insINS

Utility instruction routine. Creates and inserts an instruction into the current block in one call.

SymReg *get_pasm_reg

get or create the SymReg

SymReg *get_const

static Instruction *pcc_get_args

set arguments or return values get params or results used by expand_pcc_sub_call and expand_pcc_sub

static void unshift_self

void expand_pcc_sub
