So the problem was the CCS6 settings defaulted to "elf" output format, but
the original build was in "legacy Coff". The reason why the change of
output format from "legacy COFF" to "eabi (ELF)" causes the code size bloat
is that the code calls log10, sqrt and pow which take double arguments. In
COFF double is 32-bits but is 64-bits in ELF. So the issue was .text was
looking like it was trying to be placed at 0x0 in the map file, but 0x0 was
just a placeholder as the code would not fit. Change the output to "legacy
Coff" and the project builds fine...
