0f010430cc + better precision in determining the registers, read by mul/imul/div/idiv in

916c09af55 + also check the register type when checking for specific integer registers in 
i386's TCpuAsmOptimizer.RegReadByInstruction. Previously, the lack of this
  check could generate false reads on some other register types (e.g. mmx/xmm/
  flags, etc.), and this could worsen optimizations.

1d34e96064 + added x86 instruction flag Ch_RFLAGScc, indicating instructions that read

869f395a31 + added knowledge to the compiler for the x86 instructions, that don't read

nickysn
9303a8f61a * changed the x86 TInsProp.Ch structure from a 3-element array to a pascal set; 
this removes the limit of 3 Ch_XXX flags per instruction (thus allowing adding
  more precise flags, e.g. for tracking only certain bits of the flags register,
  etc.) and avoids the ugliness of having the Ch_None filler, which makes
  x86ins.dat less readable.

189e49998c * fixes to the x86 instruction flags tracking attributes: 
* AAA and AAS also read flags (AF)
  * CMC reads and writes flags (it inverts CF)
  * CMPSx and SCASx write flags
  * CMPSx, SCASx, LODSx, STOSx, MOVSx read the direction flag
  * NOT doesn't affect flags
  * REP isn't affected by and doesn't affect flags
  * REPE/REPNE/REPZ/REPNZ/REPC/REPNC don't write flags, only read them
  * ROL and ROR don't read flags
  * SAL doesn't read flags
  * SHLD and SHRD don't read flags

e708a76f70 * some i386 optimizations for 64-bit SHL/SHR/SAR in tcg64f386.a_op64_const_reg:

d7b8d8dd54 * don't emit the "SUB ECX,32" instruction on i386, when doing a 64-bit shift by 
reg, with a value >=32. The instruction is redundant, because the SHL/SHR
  instructions already AND mask the shift count by 31.

256dc546ac + implemented the in_neg_assign_x and in_not_assign_x inline nodes, which will 
be used (TBD in a future commit) for optimizing x:=-x and x:=not x on CPUs
  that support performing these operations directly in memory (such as x86)

6580dfee39 * generate better i386 code for 64-bit shl/shr, by masking the shift count by 
63, instead of comparing it to 64 and branching. Note that, although this
  changes the behaviour of 64-bit shifts by values larger than 64 (when stored
  in a variable), it actually makes them consistent with both the code,
  generated on x86_64, as well as with 64-bit shift by constant on i386 itself.

4c68ea1000 * use pocalls_cdecl and cstylearrayofconst more consistently instead of 
ad hoc set constants containing varying number cdecl-like calling
    conventions
   o added pocall_sysv_abi_cdecl and pocall_ms_abi_cdecl to cstylearrayofconst
   o also allow C-style blocks with mwpascal instead of cdecl (mwpascal = cdecl
     with "const" = "constref" for record parameters)
   o did not touch cases related to name mangling and import/export names,
     because those are a real mess and easily break things left and right :/

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now

    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of

  Prior the fix I have not been able to compile even RTL with -O2 due to not enough free registers, since EBX is reserved for GOT.

26b53607f8 + added method reference_reset_base with support for different pointer types to 
the high level code generator. All hlcg code, except for the jvm code
  generator, updated to use the new method. I didn't update jvm (it still uses
  the method from cgutils), because I'm not familiar with that platform, so I
  might get the types wrong.

179586f589 + SEH support for Win32. Enable by cycling with OPT=-dTEST_WIN32_SEH. 
Although basic things work (no regressions in test suite, also with TEST_OPT=-O2), there are some secondary issues/TODOs:
- Exception frame around PASCALMAIN is not properly removed in DLLs
- No stack traces yet
- Stack overallocated in finalizer procedures, their entry/exit code needs cleanup
- Signals unit is probably completely broken.
