| CODEGEN-2010 |
Decomp error involving packed class |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.2.LTS |
|
Fixed an issue that could result in a "Decomposition error" abort of the compiler. |
| CODEGEN-1976 |
Value of __cplusplus is wrong |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.2.LTS |
If possible, use the -ps or --strict_ansi options. This mode will use the strict definition of __cplusplus, which is 199711L. |
Our parser mimicked G++ behavior for the value of this macro in relaxed ANSI mode. This reproduced a bug in G++ versions v.4.7 and v.4.3 that has since been fixed. |
| CODEGEN-1703 |
Designated initializer plus struct hack hangs compiler |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.1.LTS |
Avoiding using string constants to initialize objects with flexible array members. Instead, use a brace-initialized array. For example:
struct { int a; char b[]; } mystruct = {0, {'h', 'e', 'l', 'l', 'o'} }; |
Fixed a compiler hang caused by initializing flexible array members with string constants.
struct {int a; char b[]; } mystruct = {0, "hello"} /* Would cause the compiler to hang and/or crash */ |
| CODEGEN-1649 |
Warning "INLINE recursion limit exceeded" during RTS build |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.0.LTS |
None, for the automatic library builds. Elsewhere, one can use the hidden --inline_recursion_limit option to increase the limit above the default 10. |
The compiler may emit the warning "INLINE recursion limit exceeded," but there is no way to suppress the warning, and it really isn't useful for the typical compiler user. These changes remove the warning. |
| CODEGEN-1640 |
MISRA 19.1 misreported: #include statements should only be preceded by other preprocessor directives |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.1.LTS |
No practical workaround |
|
| CODEGEN-1634 |
MISRA 7.1 misreported: octal tokens in token paste |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.1.LTS |
No practical workaround |
|
| CODEGEN-1632 |
MISRA 15.2 misreported: switch clause unconditional break |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.1.LTS |
Put an explicit break at the end of the compound statement |
|
| CODEGEN-1517 |
#pragma FUNCTION_OPTIONS meaningless unless at least -o0 is used |
Fixed |
|
MSP430_16.9.0.LTS |
|
|
| CODEGEN-1433 |
MSP430 assembler may internal error for symbol defined differently in each pass when forward referencing a label |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.1.LTS |
Do not use a forward reference of a label. |
A forward reference of a label by an instruction that may use the constant generator (such as a move) in assembly may cause the position of a later label to be "defined differently in each pass," an internal error in the assembler.
|
| CODEGEN-1417 |
User error in _symval call causes compiler to issue INTERNAL ERROR: no match for ICALL |
Fixed |
|
MSP430_16.9.0.LTS |
|
|
| SDSCM00052904 |
Unsigned array index not truncated properly in array indexing expression |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.2.LTS |
None |
An unsigned integer multiplication used in an array indexing expression was erroneously optimized into instructions performed in 20 bits instead of 16 bits, thereby failing to truncate an overflowed value into zero. |
| CODEGEN-1333 |
Structure assignment causes compiler to fail with INTERNAL ERROR: Decomposition error |
Fixed |
|
MSP430_16.9.0.LTS |
Replace struct assignments involving packed structures with a memcpy() call to copy the contents of the RHS of the struct assign to the LHS. |
|
| CODEGEN-1297 |
Incorrectly issues ULP 8.1 diagnostic |
Fixed |
|
MSP430_16.9.1.LTS |
N/A. |
The compiler throws an invalid ULP 8.1 diagnostic in the case below:
% type try1.c
void test2(char buffer[5])
{ buffer[0] = 'A'; }
void test(void)
{
char buf[5] =
{ 0 }
;
test2(buf);
}
% cl430 --advice:power try1.c
"try1.c", line 8: remark: (ULP 8.1) variable "buf" is used as a constant. Recommend declaring variable as either 'static const' or 'const' |
| CODEGEN-1292 |
MSP --near_data revert linktime optization fix from CQ52683 due to code size degradations |
Fixed |
|
MSP430_16.9.0.LTS |
Ensure that the same --near_data option is used for all object files and libraries in the link. |
A relocation error may occur during link time optimization if --near_data has been specified with different values for different translation units. Earlier change in SDSCM00052683 introduced code size degradations and has been reverted. |
| SDSCM00040386 |
Remove -olength option from hex utility's help summary and Users Guides |
Fixed |
MSP430_16.9.0.LTS |
MSP430_16.9.0.LTS |
|
|
| SDSCM00052153 |
Remove compiler option --gen_func_subsections from MSP430 compiler user's guide |
Fixed |
|
MSP430_16.9.0.LTS |
|
The --gen_func_subsections option should be removed from the MSP430 compiler user guide. Function subsections are always generated for MSP430. |
