Hydrogen Assembler 0.2.x

[AaronMiller]

That looks cool. Looks like it'll be quite useful. If you want any help with the assembler or your language (or w/e) let me know.

EDIT: Is it case sensitive?

I do not need help for now, thanks! I just need some testers...

EDIT: Is it case sensitive?

Instructions are case insensitive, and symbols are case sensitive (like HyASM).

[AaronMiller]

Okay, cool. Good luck!

New release: 0.2.5.

What's new?
- fixed a critical bug with DB and strings.
- MIPS: added new instructions.
- added specific variables:
OFFSET: get the offset in the current section.
BASEADDR: get the base address of the application.
SECTADDR: get the base address of the current section.
SECTSIZE: get the size of the current section.

Hi Tommy,
In the console example I tried to automatically calculate the length of the string:

Code: Select all

Hello:	db	"Hello, world!", 13, 10
Length	equ	$ - Hello

This caused the following error:

Code: Select all

Error: console.asm(55): invalid instruction or directive ("Hello").

Is this something still to be implemented?

Nice start with the manual. I think it's complete enough for people already familiar with assembly language. I'm not sure if I understand the RELATIVE operator though, and should OFFSET really be relative to some section?

HyASM doesn't support yet the '$' operator. I don't like the "name" : $. I should find a name more understandable,
like "ADDRESS" or something like that. I think I will made a new release today. Other thing, expressions must be
placed between parentheses.

The RELATIVE operator is equivalent to the RVA operator in FASM. It get the relative address of a symbol to the base address
of the application. The manual will be updated, RELATIVE is not a variable. OFFSET contains the current offset in the
section. To be clear: OFFSET = $ - SECTADDR.

OFFSET contains the current offset in the section. To be clear: OFFSET = $ - SECTADDR.

This differs a lot from the OFFSET operator in MASM and TASM syntax, doesn't it? I mean, the next two are equivalent in MASM but not in HyASM:

Code: Select all

	push	dword Hello
	push	offset Hello

(Not that MASM accepts "dword <symbol>" but you get the idea.)

In MASM/TASM, the OFFSET operator is used to get the address of a symbol. This is very different.

I forgot to implement something in HyASM: the EQU operator doesn't support expressions.
Will be fixed today.

New release: 0.2.6.

What's new?
- fixed a critical bug in expressions.
- EQU directive can handle expressions.
- added new assembler variable (ADDRESS).
- added new expressions operators:
& : bitwise AND
| : bitwise OR
^ : bitwise XOR
<< : bit shift left
>> : bit shift right
< : rotate left
> : rotate right

Perhaps I will begin my other project of a new programming language...

Perhaps I will merge this project to HyASM to provide a new high-level assembler syntax...

In MASM/TASM, the OFFSET operator is used to get the address of a symbol. This is very different.

Then I think you shouldn't call it OFFSET. It's confusing. How about INSECT?

INSECT?



About the MASM's OFFSET, it's confusing, yes, but I will not change. OFFSET means the current offset in section.
And in HyASM, OFFSET is not an operator. Or, I add one character before each variable to avoid confusion.
How about $OFFSET, #OFFSET... ?

[AaronMiller]

I like $OFFSET.

[phredreeck]

I like $OFFSET.

OK. Will be changed for version 0.3.0.
