ba4343d9d1 Added support for Immediate mode 16 bit 
Currently only afi instruction is encoded, will be adding other instructions too. For encoding we are running out of characters so was planning to append the complete modes (RXa or rxa) which one do you think is better, and also thinking of just adding remaining instruction modes as well, which we don't support as of now. Let me know if you want me to add those, or we will wait for sometime before we add those.

be3efbc65a Add simple tests for RX and RXY style instructions. 
Also changed the test function signature to int64_t fn(int64_t, int64_t)
to make it easier to test 64-bit operations.

d9e61fe7a8 Shorten templates by four characters. 
We only have 6-byte instructions, so we don't really need the ability
to encode 8-bytes.

54199bd9bc Clean up test file and add script to run tests. 
./run.sh will now execute the tests. It is a very simple setup
currently, and is limited to linux on s390x. Enough to get started
with.

2324be897e Reduce indentation level of big switch statement. 
A style thing. I find it easier to read this way.

i.e. do:

while(1) {
  if (blah) {
    ...
    continue;
  }
  ... // big switch statement
}

instead of:

while(1) {
  if (blah) {
    ...
  } else {
    ... // big switch statement
  }
}

fc2b633532 Auto-format dasm_s390x.h. 
I did this mostly to get rid of the annoying tabs/spaces mix in this
file. It has the side effect of forcing newlines before statements
which I think is a better style (and not particularly inconsistent
with the original which used both styles). Other than that I've tried
to match the original style as closely as possible.

Generated with this command:

indent -i2 -brs -cli0 -br -ce -npcs -nbc -di1 -npsl -ncs dasm_s390x.h

f0dd40dc50 Adding support for Immediate add mode 
The masking in immediate mode might not be proper. I could understand that you had masked 12bits and then 8bits to get the displacement in place for 20-bit displacement ( cp[-2] |= n&0xfff;          cp[-1] |= (n>>4)&0xff00;)  But in my case I need all the 32bits, so not sure how to go about it. Currently I have just used "n" since no point in "and with 0xffff" But I am getting core dump. Please Let me know your comments on these.

77f283c328 Allow symbols to be used for 12-bit displacements. 
The parse_mem_bx function now returns a function to call to add an
action to the action list to handle the evaluation of the
displacement. This allows us to delay adding said action until
after we have emitted the actions for the instruction encodings
themselves.

Code like this should now work:

int x = 24
| st r1, x(sp)

a34bcf9ef4 Add initial support for D(B,X) memory operands (12-bit only). 
Most RX instructions don't specify the correct number of operands
so this won't work on many yet. It also won't yet emit an action
if D is a variable rather than a constant.

cf225d27cc Fix C code in header file and handle br template. 
This means that code like this can now be generated on s390x:

| ar r2, r3

Still need to add support for immediates, memory, labels, other
instructions and so on.

000b1a84f0 Breakup instructions and action list into halfword chunks. 
This should allow us to encode the instructions relatively naturally
and efficiently. For now I've escaped halfwords with a value <=
the maximum action. This means that 0 is escaped which probably
isn't ideal, so we may want to revisit that decision at some point.
 2016-11-29 18:06:59 -05:00
Michael Munday
d97dea2e3f Add a description of how immediate actions should be encoded. 
Also sets the action list type to unsigned short (uint16_t) which
I think is the most appropriate type for s390x (x86 uses uint8_t
and other platforms use uint32_t).

89ca41cca5 Add sp -> r15 mapping and don't special case or_2 
It's convenient for sp to be a pseudonym for r15 (the stack pointer).
'or_2' doesn't need to be special cased ('or' did because it is a
keyword).

7a49be07be Added the required character for encoding 
I have added the number depending on the number of operands, pls check for the ones which access memory.
Also For base register and displacement, should I assume that it will be passed in the same order as it is expected, since I dont have any means to see the output, I am confused a bit for those add modes.
Since we decided to test RR first, thats in progress, but would like to add others as well.

203006579f Removed the extra check in parse_reg 
The extra check for register is currently ignored, and trying to see what value does the encode function return. Its still to be worked out, how this value is used later, after decoding.
