I am trying to write a loop macro to read in a set of data into xmm registers
(I am using 64 bit assembly, so I DO have xmm0..xmm15)
FOR arg, <0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15>
movdqu @catstr("xmm", <arg>), [rcx + (arg)*16]
ENDM
I get the error:
error A2206:missing operator in expression
Am I calling catstr wrong? If not, what is the macro actually expanding to?
Is there a way I can see the asm text generated by MASM post-macros?
literals must enclosed by <...> instead of "...". Your task can be solved without @CatStr:
FOR arg, <0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15>
movdqu xmm&arg, [rcx +(arg)*16]
ENDM
For debugging macros, you can use listings: ml.exe ... /Fllist.txt /Sn
Place the .nolist-directive at the first line of your source code. Immediately before the point of interest add .listall
Thank you, that worked perfectly!
Is there a way to write the loop without explicitely listing all the cases,
something like
For i=0:15
....
endM
cntr = 0
WHILE cntr LT 16
@CatStr(<movdqu xmm>,%cntr,<, [rcx + >,%cntr*16,<]>)
cntr = cntr + 1
ENDM
Also, I got an error when trying to do:
ml64.exe myAsm.asm /Fllist.txt /Sn -> list.txt
It creates list.txt with the contents "MASM : warning A4018:invalid command-line option : -"
I added the "." commands into the file like you told me
Quoteml64.exe /Fllist.txt /Sn myAsm.asm
syr, that was ambiguous
ml64.exe myAsm.asm /Fllist.txt /Sn -> list.txt
ml64.exe myAsm.asm /Fllist.txt /Sn > list.txt
Do you know of a way to do a similar compile-time macro in c++?
...Oops, sorry,...nevermind,...I don't know what I'm talking about,...comment deleted,... :eek

AFAIK it is not possible with loops, beacuse the cpp preprocessor doesn't have macro-loops. However, simply creating a macro, which hold 16 corresponding lines (movdqa ..,xmmX...) is possible.
I am trying out the .IF statement and running into trouble using ml64.exe
.IF R8==16
mov rax,5
.ELSE
mov rax,2
.ENDIF
A similar question was asked here: http://social.msdn.microsoft.com/Forums/zh/vclanguage/thread/3f8aa123-64ca-4623-9ebb-11aa811ee428
They concluded that the .IF was removed from ml64. Is there another built in keyword that does similar branching?
The errors I get are:
Transpose16x16A.asm(100) : error A2008:syntax error : IF
Transpose16x16A.asm(102) : error A2008:syntax error : .
Transpose16x16A.asm(104) : error A2008:syntax error : .

no. Using the forum search, you maybe finder some macros that do this.
You should switch to jWasm, which has all this capacities: ml64.exe is mutilated version of ml.exe.
Thanks, I will look into jWasm.
Isn't ml64 just the 64 bit version of ml, so ml wouldn't be able to compile 64 bit assembly?
It is, it is, but M$ decided that compilers have no need for .if ... .endif and all that, so they dropped high level language elements. Use JWasm, it's a perfect clone, much faster, too.
