Macro Definition Documentation

REX_EXTERN

#define REX_EXTERN

(

x

)

Value:

extern "C" REX_FUNC(x)

Declares a recompiled function with C linkage.

Parameters

x	The C++ symbol the generated code defines and calls.

REX_EXTERN(sub_82010000);

REX_FUNC

#define REX_FUNC

(

x

)

Value:

void x([[maybe_unused]] PPCContext& __restrict ctx, [[maybe_unused]] u8* base)

Declares a recompiled function with no linkage specifier.

Parameters

x	The C++ symbol the generated code defines and calls.

REX_FUNC(sub_82010000);

REX_RECOMPILED_CODE

#define REX_RECOMPILED_CODE

(

)

Value:

::std::span<const ::rex::u8>(__start_rexguest, __stop_rexguest)

Returns the recompiled code section of the image that expands it.

rex::ppc::AddRecompiledCode(REX_RECOMPILED_CODE());

REX_RECOMPILED_CODE_SECTION

#define REX_RECOMPILED_CODE_SECTION   __attribute__((section("rexguest")))

Places a function in the recompiled code section, where a stop may redirect a thread.

Variable Documentation

__start_rexguest

const ::rex::u8 __start_rexguest[]

The first byte of the recompiled code section, null when the image has none.

__stop_rexguest

const ::rex::u8 __stop_rexguest[]

The byte past the end of the recompiled code section, null when the image has none.

kPPCFuncMappings

const PPCFuncMapping kPPCFuncMappings[]

extern

Guest to host function mappings, defined by the generated code.
