/*
|
|
These functions convert data that contain CPU instructions.
|
|
Each such function converts relative addresses to absolute addresses in some
|
|
branch instructions: CALL (in all converters) and JUMP (X86 converter only).
|
|
Such conversion allows to increase compression ratio, if we compress that data.
|
|
|
|
There are 2 types of converters:
|
|
Byte * Conv_RISC (Byte *data, SizeT size, UInt32 pc);
|
|
Byte * ConvSt_X86(Byte *data, SizeT size, UInt32 pc, UInt32 *state);
|
|
Each Converter supports 2 versions: one for encoding
|
|
and one for decoding (_Enc/_Dec postfixes in function name).
|
|
|
|
In params:
|
|
data : data buffer
|
|
size : size of data
|
|
pc : current virtual Program Counter (Instruction Pinter) value
|
|
In/Out param:
|
|
state : pointer to state variable (for X86 converter only)
|
|
|
|
Return:
|
|
The pointer to position in (data) buffer after last byte that was processed.
|
|
If the caller calls converter again, it must call it starting with that position.
|
|
But the caller is allowed to move data in buffer. so pointer to
|
|
current processed position also will be changed for next call.
|
|
Also the caller must increase internal (pc) value for next call.
|
|
|
|
Each converter has some characteristics: Endian, Alignment, LookAhead.
|
|
Type Endian Alignment LookAhead
|
|
|
|
X86 little 1 4
|
|
ARMT little 2 2
|
|
ARM little 4 0
|
|
ARM64 little 4 0
|
|
PPC big 4 0
|
|
SPARC big 4 0
|
|
IA64 little 16 0
|
|
|
|
(data) must be aligned for (Alignment).
|
|
processed size can be calculated as:
|
|
SizeT processed = Conv(data, size, pc) - data;
|
|
if (processed == 0)
|
|
it means that converter needs more data for processing.
|
|
If (size < Alignment + LookAhead)
|
|
then (processed == 0) is allowed.
|
|
|
|
Example code for conversion in loop:
|
|
UInt32 pc = 0;
|
|
size = 0;
|
|
for (;;)
|
|
{
|
|
size += Load_more_input_data(data + size);
|
|
SizeT processed = Conv(data, size, pc) - data;
|
|
if (processed == 0 && no_more_input_data_after_size)
|
|
break; // we stop convert loop
|
|
data += processed;
|
|
size -= processed;
|
|
pc += processed;
|
|
}
|
