+ Add for loop code optimization using notifications
results in 1.5-1.9% speed improvement in nestloop benchmark
Optimization incomplete, compiler does not cycle yet with
notifications enabled.
is only allowed for the same name
* varsyms are inserted in symtable before the types are parsed. This
fixes the long standing "var longint : longint" bug
- consume_idlist and idstringlist removed. The loops are inserted
at the callers place and uses the symtable for duplicate id checking
+ Added read/write notifications of variables. These will be usefull
for providing information for several optimizations. For example
the value of the loop variable of a for loop does matter is the
variable is read after the for loop, but if it's no longer used
or written, it doesn't matter and this can be used to optimize
the loop code generation.
* symtable.insertvardata/insertconstdata added
* removed insert_in_data call from symtable.insert, it needs to be
called separatly. This allows to deref the address calculation
* procedures now calculate the parast addresses after the procedure
directives are parsed. This fixes the cdecl parast problem
* push_addr_param has an extra argument that specifies if cdecl is used
or not
+ ret_in_reg to replace ret_in_acc
(fix some register allocation bugs at the same time)
+ save_std_register now has an extra parameter which is the
usedinproc registers
+ tprocessor enumeration moved to cpuinfo
+ linker in target_info is now a class
* many many updates for m68k (will soon start to compile)
- removed some ifdef or correct them for correct cpu
* asmsymbollist global is removed and moved into a new class
tasmlibrarydata that will hold the info of a .a file which
corresponds with a single module. Added librarydata to tmodule
to keep the library info stored for the module. In the future the
objectfiles will also be stored to the tasmlibrarydata class
* all getlabel/newasmsymbol and friends are moved to the new class
