Started using ml64 recently to port some extended precision arithmetic code to 64 bits.
Able to integrate things into a visual studio project.
However I've encountered a really annoying problem - how do I get ml64 to recognize hexadecimal immediate values??
For example:
mov rax,fffffffffffffffeh
(attempting to move 64 bit value into rax)
generates the error:
error A2006:undefined symbol : fffffffffffffffeh
Decimal constants work fine. I thought appending an 'h' to a hex constant would work? - help
Try mov rax,0fffffffffffffffeh
an short addition: for most compilers and assemblers numeric values must begin with an digit (0-9)
thank you, apparently need a zero in front of the immediate value.
.......... in order to differentiate them from labels
labels must not begin with a (0-9) numeric digit
this includes names for data, code, constants
when you say "fffe", the assembler is looking for a label
Eric,
Put a "0" at the front of the hex notation, this is normal in MASM where a number must have a leading digit.
mov rax, 0FFFFFFFFh
