CODEGEN-5174 Error in workaround for CODEGEN-3721 Fixed C2000_18.9.0.STS Rewrite the code to avoid "<=" or ">=" integer comparisons. This may not always be possible, because the optimizer may rearrange other integer comparisons to create "<=" or ">=" comparisons. Integer <= and >= comparisons may falsely return "true" for some inputs. This will only happen for inputs that have more than 24 significant binary digits but vary in the lowest bits. The more significant binary digits the values have, the more bits may vary in the lowest end of the values and still falsely compare equal.
CODEGEN-4721 Linker crashes with INTERNAL ERROR: lnk2000 experienced a segmentation fault Fixed C2000_18.9.0.STS C2000_18.9.0.STS None. In the right (or wrong) circumstances, the linker may crash or print an error message and exit. The immediate reason is memory corruption caused by an errant data structure, which means that it's very hard to specify exactly how to reproduce or avoid it. There is no known workaround.
CODEGEN-4668 Macro with temp label causes assembler to crash Fixed C2000_18.9.0.STS The problem will not occur without macro labels. If labels are required, no workaround is known. The assembler may crash or report a memory misuse when using an assembly macro containing a label, if the label appears in an instruction in a position that requires extra lookahead to parse. The original example is a register name followed by a comma and a label use; for that assembler, the thing following the comma might be a shift specifier, so it requires expanding the macro label. That extra step frees some memory that it shouldn't, causing the problem.
CODEGEN-4600 Warning when using pragma RETAIN with attribute((noinit)) Fixed C2000_18.9.0.STS C2000_18.9.0.STS When using pragma RETAIN with attribute((noinit)) on the same symbol for an EABI target, a .clink directive is erroneously emitted in the assembly file, leading to a warning that the .CLINK directive is being ignored because the symbol already has .RETAIN specified.
CODEGEN-4496 CLA compiler passes function arguments incorrectly and issues linker error Fixed C2000_18.9.0.STS C2000_18.9.0.STS None The CLA linker issues an undefined symbol error for a CLA math library function's scratchpad (__cla_CLAsincos_sp). The fundamental bug is that the CLA code generator is erroneously passing a function argument on the function's scratchpad even though it should be passed in a register, and then zeroing out the register. Additionally, the function is a CLA math library function which has defined an incorrect scratchpad name, so once the function's scratchpad is referenced, the linker issues an undefined symbol error because there is no definition for the legitimate function scratchpad name. However, the function's scratchpad should not be referenced to begin with. The bug was introduced in C2000 CGT v17.3.0.STS.
CODEGEN-3595 Stack usage under reports stack amount used because it fails to handle function aliases Fixed C2000_18.9.0.STS CCS Stack Assistant did not accurately track aliased functions-- functions whose definitions are represented by a different symbol name. Now, the alias function will be used to determine stack size correctly, and the aliased function call name will be replaced with its alias. Currently, the Stack Assistant GUI is not capable of showing both the aliased and alias function names for calls to aliased functions-- this will require a future update.
SDSCM00014430 calloc doesn't check arguments to make sure the requested size is reasonable Fixed C2000_18.9.0.STS
