OrcCompiler

OrcCompiler — Compile Orc programs

Types and Values

Description

OrcCompiler is the object used to convert Orc programs contained in an OrcProgram object into assembly code and object code.

The OrcCompileResult enum is used to indicate whether or not a compilation attempt was successful or not. The macros ORC_COMPILE_RESULT_IS_SUCCESSFUL() and ORC_COMPILE_RESULT_IS_FATAL() should be used instead of checking values directly.

When a program is compiled, the compiler calls the functions contained in various OrcRule structures. These functions generate assembly and object instructions by calling ORC_ASM_CODE() or functions that use ORC_ASM_CODE() internally.

Functions

ORC_COMPILER_ERROR()

#define             ORC_COMPILER_ERROR(compiler, ...)


ORC_COMPILE_RESULT_IS_FATAL()

#define ORC_COMPILE_RESULT_IS_FATAL(x) ((x) >= 0x200)


ORC_COMPILE_RESULT_IS_SUCCESSFUL()

#define ORC_COMPILE_RESULT_IS_SUCCESSFUL(x) ((x) < 0x100)


ORC_ASM_CODE()

#define ORC_ASM_CODE(compiler,...) orc_compiler_append_code(compiler, __VA_ARGS__)


orc_compiler_append_code ()

void
orc_compiler_append_code (OrcCompiler *p,
                          const char *fmt);

Generates a string using sprintf() on the given format and arguments, and appends that string to the generated assembly code for the compiler.

This function is used by the ORC_ASM_CODE() macro.

This function is useful in a function implementing an OrcRule or implementing a target.

Parameters

p

an OrcCompiler object

 

fmt

a printf-style format string

 

orc_compiler_label_new ()

int
orc_compiler_label_new (OrcCompiler *compiler);
