How do I control the size of the push instruction in MASM 5.0+?
push 42 ; I need this to be 2 bytes: opcode + 1 byte of data.
push 42 ; I need this to be 5 bytes: opcode + 4 bytes of data.
In NASM it's push strict byte 42 and push strict dword 42. I'm looking for the MASM equivalent.
This seems to work in Microsoft (R) Macro Assembler (x64) Version 14.37.32822.0
push byte ptr 42
push word ptr 42
push dword ptr 42
push 42
The opcodes generated are
6a2a push 2Ah
66682a00 push 2Ah
682a000000 push 2Ah
6a2a push 2Ah
The stack layout is
000000da`eb36fbf6 000000000000002a
000000da`eb36fbfe 000000000000002a
