No. a47
The linker option –codefactor breaks the code in interrupt functions when code is
optimized for speed
Version Information
V4.0.5, V4.0.5c
Details
The linker option -codefactor modifies the prologue of an interrupt routine in a way that writes on
r6 and r7. This is correct in non-interrupt routines but not here, overwriting those registers might
cause the code to break
Command Line
ccv850e –codefactor – Ospeed
Workaround
Use new compiler Version 4.07.
No. a48
Any macro containing a sequence with a '.' followed by other characters is not expanded
correctly.
Version Information
V3.5, V4.0.5, V4.0.5c
Details
When a macro like this:
#define LEAF( name) .section name;
is expanded by the preprocessor, the result is a white space separated text like this
. section name
Workaround
1. Use option “–option=98” to preprocess as expected.
2. Use new compiler Version 4.07.
