|
|
TI cgt6x is a compiler suite for TI DSPs.
|
|
|
|
The toolchain does pretty weird things, and I'm sure I'm missing some of them.
|
|
But still, the tool saves time.
|
|
|
|
What this tool does is:
|
|
|
|
- create a TI compiler environment
|
|
- create TI compiler features, to handle some specifics about this compiler
|
|
It has a few idiosyncracies, such as not giving the liberty of the .o file names
|
|
- automatically activate them when using the TI compiler
|
|
- handle the tconf tool
|
|
The tool
|
|
|
|
TODO:
|
|
|
|
- the set_platform_flags() function is not nice
|
|
- more tests
|
|
- broaden tool scope, if needed
