picasso v2.7.1

• Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience.

picasso v2.7

v2.7

• Added dst, litp and break instructions (thanks to @Tilka).
• Added check to enforce index regs being used only with floating point vector uniforms.
• Renamed index registers to match D3D naming conventions (a0.x, a0.y, aL) (old names still accepted).
• Miscellaneous bugfixes and improvements (thanks to @lioncash).

v2.6.2

• Fixed several compilation errors in some compilers.

v2.6.1

• Reduced mad opdesc allocation errors by automatically swapping out of bounds opdesc entries with other ones in the addressable range (5 bits).

v2.6

• Added .in directive for explicit specifying (and allocating) input registers and exporting them in the DVLE uniform table.
• Added support for dollar signs ($) in identifier names, which are translated to period characters (.) in DVLE uniform names.
• Output registers o7 through o15 are now allowed in vertex shaders (as dummy outputs).
• DVLE uniform table is now sorted by register position.

v2.5

• The .gsh directive has been enhanced to provide full support for all geometry shader operation modes (point, variable-sized primitive and fixed-size primitive). This also effectively separates vertex shader uniform space from geometry shader uniform space.
• The .out directive has been enhanced to allow wiring semantics to any arbitrary output register. Additionally the dummy semantic was added while the 7 semantic was removed.
• Added auto-insertion of NOP instruction in corner cases involving flow of control instructions, together with the --no-nop directive which instead of adding NOPs warns the user about the corner cases.
• Added support for rgba and stpq in addition to xyzw.
• Added an error message for invalid input register use (e.g. add r0, v1, v2).
• The operand descriptor allocation algorithm has been enhanced to take into account unused operands.
• The 6 and 7 conditional operators have been removed since they actually do not exist.
• Really corrected MAD instruction encoding.
• Several miscellaneous issues were fixed.

v2.4

• Corrected MAD instruction encoding.
• Added command line flag for retrieving the picasso version.

v2.3

• Added .constfa for creating floating-point vector constant arrays.
• Fixed .nodvle bug.

v2.2

• Added proper support for the MOVA instruction.
• Added support for inverting the condition in JMPU.
• Fixed lcnt bug.

picasso 2.1

OUTDATED - KEPT FOR HISTORICAL PURPOSES

• Fixed input file open error message.
• Fixed .constf misallocation bug.

Currently a Windows binary is being offered for download since devkitARM r45 has not been released yet. It should be placed in the folder c:\devkitPro\devkitARM\bin.

picasso 2.0

• (Breaking change) Command line format changed.
• Added support for assembling multiple shaders (DVLEs) into a single SHBIN.
• Added new directives: .entry, .nodvle, .gsh, .setf, .seti, .setb.
• Added auto-detection of inverted forms of opcodes. (Explicitly using dphi, sgei, slti and madi is now deprecated)
• Several miscellaneous bug fixes.
