CODEGEN-2119 Stack usage assistant call graph misses callee relationship for some direct calls Fixed MSP430_17.6.0.STS MSP430_17.6.0.STS The Object File Display utility failed to detect function callees when generating call graph information for functions that contain nested blocks.
CODEGEN-2113 Hex utility mishandles space in directory name of output file Fixed MSP430_17.6.0.STS MSP430_17.6.0.STS Use directory names without spaces for output files. The hex utility did not correctly handle spaces in output directory and file names.
CODEGEN-2098 Temp filename collisions on Windows with many parallel invocations Fixed MSP430_17.3.0.STS MSP430_17.6.0.STS In some cases with a large number of compilations in parallel on Windows, the compiler could create temporary files with colliding names, resulting in strange compilation failures.
CODEGEN-2060 Even though option --buffer_diagnostics is not used, compiler issues diagnostic that says it is deprecated Fixed MSP430_17.3.0.STS None The --buffer_diagnostics compiler option was deprecated as of MCU compilers v16.6.0.STS because this setting became the default behavior for the compiler. However, the option was passed to the linker and the linker issued a remark stating the option was deprecated.
CODEGEN-2053 Compiler incorrectly reorders struct assign for small, volatile structs with bit-fields Fixed MSP430_17.3.0.STS Use optimization level 0 or off (option --opt_level) For a very specific optimization, the optimizer may drop a volatile qualifier from a struct assignment. In some cases, the compiler may later perform an incorrect optimization, most commonly incorrectly reordering volatile assignments. This bug can only happen in a function compiled with optimization level 1 or higher which contains both of the following: 1) A struct assign where the destination is volatile, and the source is a known constant, and the struct contains a bit-field, and the struct is of size "int" or smaller. 2) Any bit-field access (read or write) other than as part of a struct assign or initialization expression. That is, the name of the bit-field is present in the access expression. Note that the optimizer can create this situation by inlining functions, so 1 and 2 might be in different functions in the source code. Consider a tree x = y where x and y are of type struct S. If the value of y is known at compile time (e.g. a const value), the optimizer will try to turn the struct constant into an integer constant (possibly combining bit-fields) and rewrite the tree to look like this: "(unsigned *)x = 32;" However, if y is volatile, that should be "*(volatile unsigned *)x = 32;" Because the access is not volatile, instruction scheduling could cause this instruction to drift past nearby volatile accesses.
CODEGEN-2050 Use of -o4 causes linker XML map file to have missing input_file entries Fixed MSP430_17.3.0.STS
CODEGEN-2047 CMSIS Core v5 is not compliant with TI ARM Compiler Fixed MSP430_17.3.0.STS The __INLINE macro in the TI compiler RTS linkage.h is no longer used and can be removed. CMSIS v5 defines the macro __INLINE, which interferes with the TI compiler RTS definition of the same macro in linkage.h.
CODEGEN-1976 Value of __cplusplus is wrong Fixed MSP430_17.3.0.STS 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-1954 MSP430 manual incorrectly says MSP430X devices have no writeable memory above 64K Fixed MSP430_17.3.0.STS
CODEGEN-1705 Compiler documentation and RTS disagree on function names _TI_start_pprof_collection and _TI_stop_pprof_collection Fixed
CODEGEN-1656 Using --gen_profile_info does not work with -o4 Fixed MSP430_17.6.0.STS MSP430_17.6.0.STS Lower the optimization level to -o3. Previously, link time optimization failed when profiling options --gen_profile_info and use_profile_info were specified in combination with the --opt_level=4 option. The errors were because profiling options were not supported when used in combination with --opt_level=4. Application profiling during whole program optimization is now supported. Profiling options --gen_profile_info and --use_profile_info may now be combined with --opt_level=4.
SDSCM00052878 Documentation error: #pragma pack should be lower case Fixed
SDSCM00052904 Unsigned array index not truncated properly in array indexing expression Fixed MSP430_17.3.0.STS 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.
