58019a1649 Renamed "ltdl.h" to "ltdl-bochs.h" to avoid conflicts with the include file 
that is a part of the libtool package. Updated Makefile dependencies.
TODO: check if we can get rid of the ltdl*.* files (this would be possible if
the ltdl library is always available if libtool is present).

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

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 ...

The Windows version looks almost stable, but the GTK version fails in some cases.
That's why the classic wx debugger is still available if BX_DEBUGGER_GUI is set to 0.
- added function close_debug_dialog() to handle the simulation stop case in wx
- disable all the wx debugger related code if BX_DEBUGGER_GUI is set to 1
- added enhanced debugger specific init code similar to the code in sdl.cc
- include debugger related resources on Windows

eda28b95f4 unfortunately this change is rquired to make SMAP and SMEP features to work. 
I observed ~5% emulation slowdown ... thinking about possible mitigations

this fixes TLB issue with SMAP and SMEP features.
these features introduce a new behavior when page can be inaccessible by System (CPL=0).
Current behavior is accessBits was not supporting it but legacy (from Bochs 2.3.6) was.
The wrong behavior can be observed if user access a user page and system access the same page later.
user access is fine and pass SMEP/SMA checks and stores the translation in TLB.
the system access will hit the TLB and nobody could detect that system cannot access that page.
