Compiler

Protected mode compiler bit field fix

Real/Extended mode compiler “out of memory” error fix

Added ASSUME the list of accepted assembler keywords (only handled by external assembler).

Added support for pragma startup/exit to accept a simple macro as the priority.

Added __ADDR20__ and __ADDR24__ to the automatic compiler defines.

Fixed a problem with the casting of 0 to a far pointer.

Added the _M_IX86 macro to the real mode compiler with the following definitions: 000 - 8086 100 - 80186 200 - 80286 300 - 80386 400 – 80486

Fixed problem with protected mode compiler not allowing the calling of functions using '__interrupt'.

Fixed problem in all compilers where parameters passed to an interrupt function were pushed but were not cleaned up following the return of the interrupt function.

Added support for two new warnings:

1. In C when a switch case statement bypasses the initialization of a local variable (already an error in C++)

2. When a preprocessor directive uses an undefined macro or macro replacement in an expression

Added code to better handle huge arrays with more than 64K of complex initializations.

Added new error message to detect problem with huge array initializers having fixups that span a segment boundary.

Added ability to handle pointer assignments of the form

const char _cs *ps = "hello"

without a warning when large data models and the -dc option is used.

Added support for #pragma data_seg( seg, class, group, align) where data_seg can be one of the following:

fardata_seg

farconst_seg

farnvram_seg

farbss_seg

Fixed bug involving volatile indirection.

Change to have the option to force page alignment always takes precedence over other alignment options (default or from #pragma).

Increases in compiler table sizes to prevent out of memory errors.

Arbitrary huge arrays (size is not a power of 2) are now aligned so the 64KB is an array element boundary.

Huge segments are now para/page aligned based on the real/extended address mode.

Segment packing is now designed so that data will not be added to an existing segment if it could cause the segment to wraparound.

Fixed problem with IDE not setting the precision using in floating point calculations.

Added a pragma that allows access to the new run-time library helper functions that are in segment _DATA.

#pragma ram_rtlhelpers

Disabled code that caused non-inlined templates to be emitted as PUBDEFs (causing conflicts in other modules at link time).

Disabled integer overflow checking on array index operations since code such as "int a[0x4000] = 0" could trigger it.

Debugger

USB PromJET support added

Evaluator fix for large source files

Updated JTAG interfaces

Fix to avoid cancelation of existing debugging session in multi-target projects

Fix for crash that occurs after several debug session creation/terminations

Support for Ceibo DS-186 in-circuit emulator

IDE

Fixes for .pdl file support

Updated hardware key support for Windows XP

Linker

Now allows STACK or _STACK as permitted stack segment names.

Updated the stack creation logic to check for the existence of the stack segment and create one if requested or warn if no stack is found.

Updated linker to add unique extended mode file signature

Fixed problem with the incomplete reading of matched public/external debug records.

Fixed problem where debug information in libraries was not properly excluded when the -v- option was used with the library.

Fixed bug in the output of absolute segment information in the detailed segment map.

Extended to allow greater than 64K relocations in a relocatable load module.

Fixed an issue with the handling of common segments so it behaves like the older Microsoft/Borland linkers and starts all segment contributions identified as 'common' to offset within the segment.

Added code to place the heap in the same segment name and combine/align type as the startup code.

Added warning of segment wrap around condition.

Fixed bug in command line parsing of non-alphabetic characters.

Fixed problem with the incorrect handling of DWORD aligned SEGDEF records.

Locate tool

Real mode locator configuration file parsing fix

Real mode locator LISTFILE region directive fix

Protected mode locator fix for builds via command line

Fixed a problem with TD4->OMF enumerations overflowing an internal buffer.

Extended to allow greater than 64K relocations in a relocatable load module.

Now define the macros __ADDR20__ and __ADDR24__ based on the input file type.

RTL

Run-time library exception handling fixes

Updated startup code regarding initializer structure

Added aliases to OVRFLOW/R_OVRFLW/PCPPRTL so they can overloaded by user code.

Added RAM-based RTL helpers which can be accessed using the compiler pragma. These can be used to allow all code to be in RAM when programming flash memory.

#pragma ram_rtlhelpers

Fixed bug in the distance to the _fperror function. Reworked code so that _fpinit/_fpreset are the same and can be used interchangeably.

Added support for the snprintf/vsnprintf functions.

Redid memcmp() and strcmp() to operate at full bus bandwidth. Except for the initial overhead, memcmp() runs twice as fast as previous editions. strcmp() also runs twice as fast during comparisons but has more overhead since the string length must first be determined.

Fix to skip the save of DS in huge memory model in some CSTRING RTL functions. Fixed a bug (small/medium memory models) which caused AX to be trashed when in fact the strings were equal in memcmp().

Streamlined heap code to run 5-15% faster than previous versions.

Linker	(Real-mode) Change made to detect segments that are not fully addressable, for example, a segment starting at offset 8 could be at most 64KB-8 bytes in size (Real-mode) Improved support for the handing absolute segments (Real-mode) Problem with type information parent type indices being off by one was fixed (Real-mode) Fixed a number of minor problems: (virtual offset field was off by two, member folding problem with static member fixups, type folding did not use the second half of 2 record types) (Real-mode) Fixed to allow double quotes to be used with long filenames having white space (Real-mode) Added ability to split out absolute segments from the detailed segment map Worked around a problem with bad input debug information and now issues a warning when the problem is detected Static members from C++ classes are now handled correctly Detailed segment map no longer lists zero-length segments (other than the first)
Lint	'__nonvolatile' and other Paradigm C++ key-works have been added Lint can now handle .C source files that are marked to use the CppCompile translator
Locator	(Real-mode) Fixed problem where the wrong symbol was being displayed and the warning was issued twice (Real-mode) Fixed problem with older Borland formats not handling scope record function symbol indices Added support for RDC R8800 and R1100 processors Increased the number of preprocessor include files supported to 100

The -Fp option can now be used (currently on an evaluation basis using #pragma option -Fp) to pack far undimensioned initialized arrays into optimally-sized segments. Without this option, undimensioned will always be placed in a new segment. Handling of NULL pointers has been improved, especially the comparison of near and far pointers. One thing to consider if you mix pointer types is that promotion of a NULL near pointer to a far pointer will never be NULL, it will be DS:0. Bug in 16-bit intrinsic functions that limited the size to 32KB has now been fixed. New compiler errors It is now an error to include an initializer on data that is declared as '__nonvolatile'. New compiler errors Compiler now checks and warns if constant expressions do not fit in type int (16-bits for real/extended mode, 32-bits for protected mode). A warning will be issued for const declarations that do not include an initializer, such as const int x ;.
