4686f61002 * keep track of the temp position separately from the offset in references,

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

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol():

f1d1fd4f24 * Inserted explicit typecasts in order to prevent range check errors at some places where signed and unsigned types are assigned to each other (mostly MIPS-specific, but one was necessary in generic code).

cd27d64cd5 + Support (as target-independent as possible) optimization of division by constants: 
The code generator gets two new methods, a_mul_reg_reg_pair and g_div_const_reg_reg. The first one is basically 32x32 to 64 bits multiplication (or any other size, with result having twice the size of arguments), which must be implemented for every target. The second one actually does the job, its default implementation taken from powerpc64 and is sufficiently good for all three-address targets.

+ Enabled optimized division for MIPS target, target-specific changes are under 30 lines.

4202343033 * MIPS: emit ".set nomips16" and ".set noreorder" directives for procedures declared as "assembler nostackframe", as it is done for regular procedures. Handwritten assembler routines typically utilize delay slots, and it is desirable that assembler does not mess it up.

85dd9e5789 + added a size parameter to optimize_op_const and do a sign extension of the 'a' parameter up from the specified size, so that things like (i and $ffffffff) get optimized away the same way as (i and -1)

9494fadf08 * MIPS: set pi_do_call flag for assembler procedures with stackframes, so in PIC mode it further receives pi_needs_got in PIC mode and allocates the GP save temp. 
* Deallocate GP save temp in epilogue to avoid warnings when compiled with -dEXTDEBUG
* g_concatcopy: don't check alignment, this allows single byte or word locations to be copied with 2 instructions. Larger unaligned references are supposed to be handled in g_concatcopy_unaligned instead.

9e4cc57768 * MIPS: handle 8 and 16-bit arithmetic shifts internally, by shifting argument left by 24/16 bits, followed with 32-bit arithmetic shift right by appropriately adjusted amount.
