Homebrew PICA200 shader assembler
eeda288b29
Don't use this instruction unless you know what you're doing. It does
*not* touch the if/call stacks, so the following code will behave in an
unexpected way (and cannot be fixed by inserting nops):
```
ifu true
for ...
ifu true
break
.end
.end
.else
; will be executed since the inner if is still on the stack
.end
```
breakc has the same problem but does not require a separate condition.

picasso
Introduction
picasso is a PICA200 shader assembler, written in C++. The PICA200 is the GPU used by the Nintendo 3DS.
picasso comes with a manual Manual.md that explains the shader language. example.vsh is simple example that demonstrates it.
Building
A working C++ compiler for the host is required (Windows users: use TDM-GCC), plus autotools. Use the following commands to build the program:
./autogen.sh
./configure
make
Shout-outs
- smea for reverse-engineering the PICA200, writing documentation, working hard & making
aemstro_as.py(the original homebrew PICA200 shader assembler) - neobrain for making
nihstro-assemble, whose syntax inspired that ofpicassoand whose usage of boost inspired me to make my own assembler without hefty dependencies.
