Customer Notification r20tu0003ed1812 64
No. a50
r20/r21 used by codefactor incorrectly
Version Information
V4.0.5, V4.0.5c
Details
When using the linker optimization ‘-codefactor’ with mask register options, the mask register
might be overwritten with different value.
Command Line
ccv850e –cpu=v850e -Ospace --inline_tiny_function –codefactor -r20has255. main.c
Workaround
1. Do not use ‘-codefactor’ linker optimization along with ‘–r20has255’ and ‘-Ospace’ within
Multi2000 Builder.
2. If linker (ELXR) is invoked on command line with option ‘-r20has255’ directly passed, the
generated code is correct.
3. Use new compiler Version 4.07.
