ChangeLog

0.3.3:

	- Unified error-reporting into a separate class, and changed error
    display to a more standard appearance.
  - Added support for using 'cpp' as preprocessor in addition to gasp.
    If both are used, cpp will run before gasp, to stay compatible.
  - Added commandline-argument to specify alternative for cpp.
  - Added input-parsers for gasp and cpp that reflects the original
    filename and line in errorcodes to assist debugging.
  - Wrote a RPN expression-evaluator to assist pseudo-instruction LOI.
  - Added initial CLIP operands, but without proper validation.
  - Fixed MR32 so that destination-fields are rotated properly.
  - Fixed templates for RGET and RNEXT so that they generated proper
    destination fields.
  - Added a threshold for the number of times a dynamic branch can
    execute in the register allocator. This value has been initially set
    to 16, but can be changed by the commandline-parameter '--bthres'.
    This allows programs with a lot of dynamic branches that intersect
    to resolve.
  - Fixed multi-argument operands so that they can leave a trailing
    comma at the end without issuing any error.
  - If the final code-block is not terminated by a --exit/--endexit pair,
    the code-generator will now fail as it should.
  - Added commandline-argument '--version' to show current version.
  - Fixed a inconsistency in the argument-extraction.
  - Added a library of math-routines for use with LOI.

0.3.2:

  - It's now possible to branch between code-blocks with branch-tracking
    intact. This will allow sharing subroutines between blocks.
  - Added initial support for output parameters from code-blocks.
    Currently it will only apply output parameters if the initiating
    branch for the block reaches the exit-point.
  - Ending a code-block now properly generates a termination with nop[E].
  - All currently unsupported preprocessor directives that are VCL
    specific have been filtered from code-output. (They were previously
    passed along unprocessed)
  - Fixed issue in operand-templates where an instruction that wanted a
    indirect read with an immediate offset would generate invalid code.
  - Fixed issue with destination-fields where specifying a field on the
    second (or third) argument (e.g. 'ilw VI01,0(VI00)x') argument with
    no field specified in the operand would generate an error.
  - Fixed issue involving indirect register accesses with immediates
    where GAS would complain when the immediate was omitted.
  - Added minimal extraction of memory-groups.

0.3.1:

  - Fixed issue with branching to a subroutine from separate locations,
    which caused the branch to be aborted and ignoring any code that
    followed the BAL.

0.3:

  - Refactored register-allocator, the new version now supports
    independent ranges for register-aliases and a more flexible
    handling of branches.
  - Reverted BAL to static branching as the register-allocator now
    can handle this case.
  - Added return-address tracking for integer-registers when using
    branches (to allow tracking branches into subroutines).
  - JR and JALR no longer aborts the current branch, but attempts
    to read the return-address and jump to it. If it isn't a valid
    address, the branch is aborted.
  - Added proper register inputs for both float & integer. You can
    now connect more than one alias to a register.
  - Added support for using I,P,Q,R and ACC as register inputs.
  - Added support for .name directive.
  - Added removal of dead code.
  - Added support for --cont tag.

0.2.1:

  - Unified a lot of operand templates to reduce chance of error.
  - Added simplifications for SUBA, MULA, MADDA and MSUBA.
  - Fixed register allocation issue, now encloses registers that
    are reused due to branching (loops).
  - Fix for JR and JALR, they now abort the current branch when
    reached, to avoid issues with returning from subroutines.
  - Flagged BAL as dynamic to support early aborts from JR and JALR.
  - BAL and JALR lacked the write-modifier on the register that
    contains the return address, fixed.

0.2:

  - Implemented first iteration of the dynamic branch-tracking
    register allocator.
  - Implemented .init_v?_* operands, except the range-version.
	- Added input parameter handling for entry points.
	- Added value verification for all float & integer-aliases.
	- Added value verification for direct register writes.
  - Added proper write-dependency from pseudo-instruction LOI.
  - Rewrote input-parser to remove dependencies on strtok() and
    static char buffers.
  - Fixed issues with the templates for a lot of operands.
  - Improved argument parsing in the tokenizer.
  - Corrected so that immediates do not affect the destination field.
  - Register numbers are now allowed to be variable in size.
  - Added support for C++-style comments.

0.1.1:

  - Fixed issues with OPMULA and OPMSUB, dvp-as required that the
    generated arguments contained valid(xyz) fields.
  - Had named the '.rem_v*'-declarations incorrectly, fixed
  - Fixed win32 code to generate proper temporary filenames
  - Changed error-output to use std::cerr instead of cout, to allow
    proper use of pipes.
  - Added sourcecode-comments output support (-c).
  - Renamed 'isblank()' to 'isBlank()' to avoid issues with defines
    and gcc.
  - Made the register extraction code stricter against syntax issues
		(e.g. 'iaddiu temp1, vi00dontcare, 1' compiled without errors)

0.1:

  - Initial release
