In your controller program in C:
int thevalue = 1234;
const char cmd[100];
sprintf(cmd, "m4 -DPPCVAL=%d yourfile.m4 >thecode.c", thevalue);
In your template file in M4:
.... (some code already there...) ...
asm("your assembly stuff using PPCVAL ....");
....
to make a long story short: use -D with m4 to define a macro on the command
line. Use this macro by name in your generated C code. M4 will replace the
macro by its value even when it occurs within a C string.
