147d788022 few fixes in new disasm module 2013-09-30 20:16:52 +00:00
Stanislav Shwartsman
fd383435f0 - Initial code for bx_Instruction_c disassembler which (together with Bochs decoder) will replace Bochs disasm module someday (very soon). 
The code already knows to disasm most of the opcodes with their operands.

- Split according to OSIZE opcodes RDFSBASE/WRFSBASE / RDGSBASE/WRGSBASE both for disasm and performance

- Minimize amount of opcode forms in ia_opcodes.h again.
  For example Udq means the same as Wdq but with no memory form.
 2013-09-30 19:01:42 +00:00
Stanislav Shwartsman
fa06b26c88 Make possible to deliver instruction name for disasm directly from bx_ia_opcode_name (some opcodes were renamed). 
Fixed bug in stack optimization in 64-bit mode (should result in some speedup)
ia_opcode.h - eliminate some OP_M cases when they actually meant "value of specific type in the memory"
example: "MOVBE Md, Gd" actually means "MOVBE Ed, Gd"which just not have reg/reg form.

ff79cbd596 Infrstructure change to support disasm of BxInstruction_c directly (without calling disasm) 
The end goal will be also merging of disasm and cpu decoder to one module and remove the disasm.

Two bug fixes on the way:
TBM: fixed 64-bit TBM instructions with memory access (did 32-bit load instead of 64-bit)
BMI2: fixed operands order for PEXT/PDEP instructions
AVX2: fixed gather instruction decoding bug from decoder alias commit

ef0d2142ab Allow cross-page trace linking again. 
The SMC problem was solved in following manner:

 - Every trace linked to another remembers when it was linked (a special timestamp value called traceLinkTimeStamp)
 - When true SMC happens it incremements the traceLinkTimeStamp
 - Jump to the linked trace won't be allowed if traceLinkTimeStamp in the link doesn't match traceLinkTimeStamp

So SMC effectively breaks all trace links and therefore I should not care for them anymore

5%-10% speedup on OS boot benchamarks observed

39ae66b5a3 Suppress 'entering paged real mode' CR0 check for SVM guest 
After a lot of thinking and browsing in the SVM arch forums I assume now that it shold be fine to enter to paged real mode under SVM guest.
The test case to consider:

  (paged) real mode guest -> entering Pmode (not paged) -> disabling the Pmode back

Ths assumption still should be validated with real AMD hardware

Context: AMD's manual about CR0 intercept priority :
	"Checks non-memory exceptions (CPL, illegal bit combinations, etc.) before the intercept"

The check for 'paged real mode' suposed to be illegal bit combination ...
