[1531] #align - posted: 2015-01-28 19:33:35

“	#align; - align current code to 2,4,8 boundary (dependant on architecture)

Looks like only 2,4,8 byte alignment available.

What if we need 16 byte alignment? For example, instructions:

“	MOVAPS — Move Aligned Packed Single-Precision Floating-Point MOVAPD — Move Aligned Packed Double-Precision Floating-Point

“

The MOVAPx instructions copy a vector of four single-precision floating-point values (MOVAPS) or a
vector of two double-precision floating-point values (MOVAPD) from the second operand to the first
operand — i.e., from an XMMregister or 128-bit memory location or to another XMMregister, or vice
versa. A general-protection exception occurs if a memory operand is not aligned on a 16-byte
boundary.

The #align directive is for code only, I will be adding other alignment options for variables and other data such as blocks hopefully for the next release. smile

e.g.

Code:

push eax
push ecx
push edx
#align;            // aligned on 4 byte boundary
call MyProcedure

For data, I may add several options such as

Code:

#set align 16;
DWord myVariable;
#set align 4;
Dword myVariable2;

In fact, maybe I should rename #align; to #aligncode;

and then use #align as you say... #align 16; etc... What do you think?

I think that there is many ways to implement this.

#align <value>; -- seems useable, also we can to allow #align sysword;

What about #aligncode; then
we can make all procedures/functions autoaligned by #procalign <value>;
Also we can add #loopalign <value>; for align of while\repeat loops.

May be also should use some alignment by default.

In any way it should be completely explained in our documentation of Ziron.

ok that's a good idea, maybe i will change it and add some directives.

Code:

#set code_align <x>;
#set loop_align <x>;
#set data_align <x>;
#set proc_align <x>;

etc... I will look into this, seems there is a big issue with latest release, something is broken, i guess from one of the procedure rewrites for memory operands.

Edit: This issue i have fixed, so i will take a look at this after i finish 1 new emacro feature.
