[SOLVED]Built-in assembler

[avk]

It looks like a bug, attempt to compile this code:

Code: Pascal  [Select][+][-]

1. {$asmmode intel}
2. procedure doasm;
3. begin
4.   asm
5.     test rax, $8000000000000000
6.   end;
7. end;
8.  

reports an error:

Code: Text  [Select][+][-]

1. ... Error: Asm: signed dword value exceeds bounds -9223372036854775808
2.

According to TEST instruction documentation

https://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-instruction-set-reference-manual-325383.pdf

TEST RAX, imm32

So it accepts immediate value 32 bit operand. To test with 64 bit immediate value, CMIIW, I think you need to copy 64bit immediate value to 64bit register first

Code: ASM  [Select][+][-]

1. mov rcx, $8000000000000000
2. test rax, rcx

Thank you very much.
