Section 3.12 TMS320 C28x Assembler Modes

This statement regarding TMS320 C2xx (C2xlp) compatibility is incorrect:

"The --c2xlp_src_compatible option implies the -v28 (or --silicon_version=28) option. Therefore you do not need to specify -v28 explicitly."

You must use the -v28 switch with the --c2xlp_src_compatible switch to enable compatibility. This is necessary even if the .lp_amode directive is used in an assembly source file.

Section 4.13 Directives Reference

.c28_amode/.lp_amode Override Assembler Mode

It is necessary to use the -v28 and the --c2xlp_src_compatible switch in order to use the .lp_amode directive. In other words, this assembly source:

    .lp_amode
    mar *,ar1

will not assemble if the shell is invoked as:

   cl2000.exe file.asm

   "file.asm", ERROR!   at line 1: [E0002] Invalid directive for specified processor version
   .lp_amode

The source must be assembled as:

   cl2000.exe -v28 --c2xlp_src_compatble file.asm
   
   or
   
   cl2000.exe -v28 -m20 file.asm

Section 7.8.7 Allocating an Archive Member to an Output Section

The syntax for allocating archived library members specifically inside of a SECTIONS directive is not correct in the documentation. The ONLY syntax allowed is:

[-l] library name <member1, member2, ...> [(input sections0}

As an example:

.rtstry > RAM
{
   -lrtsXX.lib (.text)
}
