AsmTK is a sister project of AsmJit library, which provides concepts that are useful mostly in AOT code-generation.
- Both X86 and X64 modes are supported and can be selected at runtime (i.e. they not depend on how your application is compiled).
- Asm parser can parse everything that AsmJit provides (i.e. supports all instruction sets, named labels, etc...).
- Asm parser can also parse instruction aliases defined by AsmTK (like
movsb,cmpsb,sal, ...). AsmJit provides just genericmovs,cmps, etc... so these are extras that are handled and recognized by AsmTK. - Assembles to any
BaseEmitter, which means that you can choose betweenAssemblerandBaseBuilderat runtime, and that the result can be post-processed as well - More to be added...
- More aliases to some SIMD instructions (to be added).
- Implement asmtk::Linker that will add the possibility to write shared libraries and executables.
Assembler parsing is provided by AsmParser class, which emits to BaseEmitter:
#include <asmtk/asmtk.h>
using namespace asmjit;
using namespace asmtk;
// Used to print binary code as hex.
static void dumpCode(const uint8_t* buf, size_t size) {
constexpr uint32_t kCharsPerLine = 39;
char hex[kCharsPerLine * 2 + 1];
size_t i = 0;
while (i < size) {
size_t j = 0;
size_t end = size - i < kCharsPerLine ? size - i : size_t(kCharsPerLine);
end += i;
while (i < end) {
uint8_t b0 = buf[i] >> 4;
uint8_t b1 = buf[i] & 15;
hex[j++] = b0 < 10 ? '0' + b0 : 'A' + b0 - 10;
hex[j++] = b1 < 10 ? '0' + b1 : 'A' + b1 - 10;
i++;
}
hex[j] = '\0';
puts(hex);
}
}
int main(int argc, char* argv[]) {
// Setup CodeHolder for X64.
Environment env(Arch::kX64);
CodeHolder code;
code.init(env);
// Attach x86::Assembler to `code`.
x86::Assembler a(&code);
// Create AsmParser that will emit to x86::Assembler.
AsmParser p(&a);
// Parse some assembly.
Error err = p.parse(
"mov rax, rbx\n"
"vaddpd zmm0, zmm1, [rax + 128]\n");
// Error handling (use asmjit::ErrorHandler for more robust error handling).
if (err) {
printf("ERROR: %08x (%s)\n", err, DebugUtils::errorAsString(err));
return 1;
}
// Now you can print the code, which is stored in the first section (.text).
CodeBuffer& buffer = code.sectionById(0)->buffer();
dumpCode(buffer.data(), buffer.size());
return 0;
}You should check out the test directory to see how AsmTK integrates with AsmJit.
