Release notes:

version 6.0.43: 9/8/2018

• occil: add this as a first class item in the project
• occil: fix various pre-existing bugs
• occ: fix problems with complex math code generation
• occ: fix problems initializing an array of objects in a constructor
• occ: qualifying a constructor with the class name (inside the class definition) resulted in bad code generation.
• occ: static cast of an argument to vector::push_back resulted in the wrong value being pushed
• occ: when stack frames are being used, presence of ONLY the thisptr isn't enough to generate the stack frame load/save
• occ: return statement could use an RREF copy on something that is in another container, effectively wiping the value.
• occ: when a 'throw' occurs from a nested routine, registers such as ESI,EDI,EBX could have been modified by the lower routines but they may not have been used in the catching routine, so the caller's values might not have been saved.
• occ: declaring an enumeration in a class resulted in bad code gen, when the -> or . operators were used to access it from an object
• occ: in function argument, an enum should prefer a match to its base type. Was prefering unsigned char. for example an enum wouldn't be translated to text characters when using streaming operators
• occ: when a function is marked as nothrow, allow it to be inlined
• occ: when a function does not have try/catch, allow it to be optimized even in the presence of an exception table

• occ: it was incorrectly adding EBP references in some cases where they weren't needed
• occ: it was not allowing inlining of functions that return a structure by reference
• occ: for subtractions with long longs, generate neg instructions if necessary to relieve register pressure.
• occ: fix problems with local variables overriding global structures
• occ: when generating line information for C++ files, line numbers were off by one.

• rtl: printf family (and by extension C++ libraries) couldn't deal with LLONG_MIN or unsigned long longs >= ULLONG_MAX/2
• rtl: the exception dump was off by one line, when the source code associated with the exception line is C++

version 4.1.12

• rtl: fix WIN32 header bug that caused CCIDE to not work reliably

version 4.1.11

• occ: remove import record from ASM file, when DLL name not specified
• occ: fix problems with statements such as:

  	typedef void AA(int b);
  	AA ss,*tt;

the typedef wasn't processed right and it resulted in errors

• rtl: work with RTL DLLs

version 4.1.10

• occ: - problem with declaring things like void (*printf)(...) in a structure would cause a redefined identifier error
• occ: problem with assigning to the first member of a structure, when the member was a pointer, would crash the compiler

version 4.1.9

• occ: there was a problem with sign extensions in statements such as p+=c where p is a pointer and c is a character value - the sign extension would be done after multiplying by the size of a pointer leading to overflow

version 4.1.8

• occ: 4.1.7 broke some programs with infinite loops

• occ: fix problem where strength reduction could be incorrectly applied when induction variables of nested loops were multiplied together

• occ: fix problem with division: sequences such as:

    	a = t %60
    	t = t / 60
    	b = t % 60
    	t = t / 60
  
    	would incorrectly generate code for:
  
    	a = t % 60
    	t = t / 60 / 60
    	b = t % 60
    	t = t / 60 / 60
  
    	because of bugs in dealing with the x86 IDIV instruction

version 4.1.4

• oasm: some floating point instructions involving memory access were generated incorrectly
• occ: floating point - use memory access more often

• rtl: rename winversion.h to winver.h

Version 4.1.2

• oasm: was generating an error when a large number was used as a byte operand to a math instruction but it was in-range for a signed value.

• occ: feature addition - OCC will look in its home directory for olink.exe

• occ: prototype warnings - only warn once, remove superfluous warnings

• occ: /O switch would add a .o extension to an executable and use it as an object file which resulted in duplicate modules being passed to the linker and linker errors. fix the /O switch to only register the exe name.

• occ: if a continuation character '' was used in strings, and it was followed by a // style comment within the string, this generated parser errors.

• occ: was filling out the entire BSS with zeros, which resulted in very large object files when there is a lot of static uninitialized data

• occ: when compile fails, delete the output file

• occ: correct code gen/register allocation/peephole optimization bugs

• olink: documentation changed to use correct target names for windows targets

• rtl: when the following was done in the source prior to including files:

    #define size_t int
  
    then there was a collision between string.h and memory.h
