Passing arguments to assembly statements in C

No.  But consider using intrinsics instead.  Intrinsics act like function calls, but are (with a few exceptions) implemented with a single instruction.

This seems like an odd reply, since it is unstated that the function I wish to implement is one that's already defined.  I wish to read a co-processor register in C, and put it somewhere, like gcc would allow me to do.

The usual method in TI C code is with a cregister, reading a memory-mapped location, or using an assembly code helper function

On C6x, to read the CSR register, you could do:

#include <c6x.h>
unsigned int csr_val = CSR;

However, the names of coprocessor registers aren't usually built in to the compiler and assembler.  How would you have named this coprocessor register if you could have used gcc-style inline assembly?  Is there a built-in name for it already, or would you have used its address?

Suppose it's memory mapped:

#define LOCATION 0x12345678
unsigned int value = *((volatile unsigned int *)LOCATION);

Obviously calling an assembly code helper function has the call/return overhead
