This releases fixes various problems with the MSDOS install and execute.

This release also replaces the x87 FPU support with SSE2.

There are also various bug fixes.

Here is a list of changes:

  • fix various problems with the MSDOS build and install
  • occ: fix stack frame in the presence of try/catch processing: don't optimize out the EBP references and don't cache variables in regs
  • occ: add __offsetof and use in library
  • occ: add __typeid and fix tgmath.h
  • occ: fix alignas and alignof, propagate section alignment through to linker
  • occ: when putting a qualifier in front of the friend keyword, the friend keyword got ignored
  • occ: fix problem with hook; when one side is a structure the other side might need a constructor call to coerce to the same type
  • occ: print return code of linker when calling --y
  • occ: faster evaluation when constexpr functions are used
  • occ: rewrite backend to use assembler core
  • occ: convert floating point calculations to use SSE2 instead of the FPU
  • occ: fix bug in assembly output when virtual function patches are applied to an overridden virtual table
  • occ: allow implicit use of captured this in lambda expressions
  • occ: fix problem with constructor initializers: direct initialization of a structure member resulted in bad code
  • occ: handle return of reference values properly, by generating an error if generating the return value requires a temporary
  • occ: c++: allow function name to be used in arithmetic expressions, warn when this is being done
  • occ: consider strings as const pointers for purposes of function argument matching
  • occ: when a member name matched a structure at global scope, various problems would occur
  • occ: assignment of constant data to a structure crashed the generated program (C++ mode only)
  • occ: when a structure is copy-constructed into a function argument, a throw in the function resulted in undefined behavior
  • occ: fix some problems with lambda functions being force fit into std::function
  • occ: fix unary operators - would apply the conversion AFTER any cast to the destination size instead of before
  • occ: fix various problems with complex and imaginary number handling
  • occ: in assembly file, represent floating point numbers as a byte sequence instead of as a decimal value
  • occ: in C++ code, allow conversion from a pointer to enum to a pointer to void in argument matching
  • occ: make operator << instantiation for ostream work with enums
  • occ: fix stdatomic.h header
  • occ: fix atomic code generation
  • occ: fix code generation for converting long long to bool
  • occ: fix static initialization of long double variables
  • occ: unsigned values promoted to int should be considered as 'signed' for purposes of division
  • occ: assignment combined with a math op did not convert the result back to bool if that is the variable type
  • occ: allow multiple use of 'const', 'volatile' keywords
  • oasm: speed up assembly of large files
  • oasm: negative floating point numbers were being represented as positive in the output
  • dlpe/oimplib: handle -y switch
  • orc: fix crash when compiled with package, when processing invalid input file
  • ocpp: (c++ version) allow # without a directive
  • ocpp: (c++ version) default to C99
  • ocpp: (c++ version) add #warning
  • ocpp: (c++ version) add __has_include and #pragma once
  • ocpp: (c++ version) reorganize sources for better interoperability with other packages
  • ogrep: add gnu-style context and stop after command line switches
  • ocide: fix function prototype popup when compiled with package, does not go away
  • ocide: when stopping on step into function, don't stop until stack frame is set up
  • ocide: when parsing RC file can't redefine keywords with preprocessing...
  • ocide: when processing strings in RC files, limit '\x##' to two hex digits
  • ocide: add orangec\bin to the path when running/debugging executables
  • ocide: empty status bar after scanning for dependencies
  • ocide: fix bad DOCKS entry in user prefs file leads to hang
  • ocide: when starting the debugger with no windows open, the disassembly window would open instead of the source file window
  • ocide: make it work when compiled against LSCRTL.DLL
  • ocide: fix crash when loading files from the command line that don't have an extension
  • olink, olib: speed up dictionary caching
  • rtl: fix recently broken strncpy to work properly again
  • rtl: fix tgmath.h
  • rtl: fix chrono::system_clock::now();
  • rtl: rewrite qsort to make it non-recursive
  • rtl: fix sprintf() and friends to print floating point numbers correctly
  • rtl: replace 80x87 math functions with cephes library
  • rtl: fix startup routines to pass correct version of hInstance to WinMain and DLLMain when compiled against LSCRTL.DLL
  • rtl: add bsd finite() functions
