CCS/TMS320F28027: Excluded ASM files not excluded by CCS when program mode compilation is enabled

Hi,

I've found that with the C2000 tools in CCS 9.0,1 asm files marked as excluded (in the project tree) are included in the compilation when the advanced compilation optimization "program mode compilation" is enabled. I can work around it by removing the .asm file, but I'd appreciate it if this bug could be resolved.

As a short example, create a C function pwm_init() and also an asm function pwm_init (in a separate .asm file):

void pwm_init() {
}
	.global _pwm_init
_pwm_init:
    LRETR

Then, mark the .asm file as to be excluded. (Note, automatic inlining needs to be disabled). I've found that in my project, a linker error is reported stating that the symbol is defined multiple times.

I'm using CCS9.0.1 with the TI compiler v18.12.1.LTS.
