I'm assuming you mean poor code generation (i.e. slow code)...
Generally speaking, few people use compilers to generate code for DSP chips
for *time critical* code sections. Note that this includes just about all
signal processing algorithms. However, you can use a high-level language
(such as C) to build the *structure* of the program and use in-line assembly
for time critical sections. I've found that this greatly enhances the
readability of the code and significantly reduces the maintenance requirements.
This `hybrid' approach is especially nice for variable passing and stack
