CODEGEN-3650 Linker crashes when printing module list to map file Fixed C6000_8.2.0 C6000_8.2.2 Add linker option --mapfile_contents=all,nomodules When creating a linker map file, and a summary of modules is written to the linker map file, and the entry point is undefined, the linker may crash.
CODEGEN-3617 gmtime incorrect when invoked in timezones east of GMT Fixed C6000_8.2.0 C6000_8.2.2 Set the timezone to 0 (UTC) until the fix is in place
CODEGEN-3613 Some vector types computations are not carried out Fixed C6000_8.2.0 C6000_8.2.2 It's possible that compiling with --opt_level=1 or greater will avoid the problem. It does in our test cases, but there are reports of cases for which that doesn't help. The problem occurs with "*pv++ = ..." where pv is a pointer to a vector. Using "pv[i] = ..." or "*pv = ...; ++pv;" seem to effectively avoid it.
CODEGEN-3597 ELF header field e_phoff should be 0 when no program header is present Fixed C6000_8.2.0 C6000_8.2.2 ELF header field e_phoff should be 0 when no program header is present, and ELF header field e_shoff should be 0 when no section headers are present.
CODEGEN-3571 Temp filename collisions on Windows in linear assembler Fixed C6000_8.2.0 C6000_8.2.2 Disable parallel builds of linear assembly source files. When compiling multiple linear assembly jobs in parallel, it is possible to get the error message: Unable to open temp macro library : %TEMP%\tempTI - Aborting
CODEGEN-2372 C2000 hex utility emits spurious warning about creating an extra output file Fixed C6000_8.2.0 C6000_8.2.2 Ignore the warning or suppress it with option --diag_suppress=21117. The Hex utility sometimes emits spurious warnings about writing data to auto-generated files.
CODEGEN-2286 palign(8) of .init_array messes up __TI_INITARRAY_Limit address Fixed C6000_8.2.0 C6000_8.2.1 In the linker command file, replace .init_array > FLASH, palign(8), fill = 0xffffffff with the following GROUP statement: GROUP { .init_array } > FLASH, palign(8) The palign(8) on GROUP will ensure that any required padding is added after .init_array. However, both the size of .init_array and the value of __TI_INITARRAY_Limit remain unchanged. Applying palign(8) to .init_array caused __TI_INIT_ARRAY_Limit to be set to the end of .init_array including the padding. This broke RTS startup code responsible for calling constructors because the table of constructors now includes invalid data. This bug has been fixed and __TI_INIT_ARRAY_Limit is no longer affected by padding.
CODEGEN-2238 Compiler incorrectly emits MISRA 10.1 for function argument Fixed C6000_8.2.0 C6000_8.2.2
CODEGEN-2119 Stack usage assistant call graph misses callee relationship for some direct calls Fixed C6000_8.2.0 C6000_8.2.0 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 C6000_8.2.0 C6000_8.2.1 Use directory names without spaces for output files. The hex utility did not correctly handle spaces in output directory and file names.
CODEGEN-1979 Statements before declarations with no white space (aggravated by macros) may cause incorrect parser error Fixed C6000_8.2.0 C6000_8.2.2 Do not start any statement in the left-most column Rearrange your code so that there are no statements before declarations. C99 and C++ allow statements before declarations in functions. This is not allowed by the C89 language, but as an extension, the TI compiler allows such statements in relaxed mode. However, in certain circumstances, the compiler may emit the 'error: expected "}"' for otherwise legal code which has statements before declarations. This problem can only occur in relaxed C89 mode (which is the default mode), and 1) you have a function with statements that start in the left-most column, or 2) you use macros where the macro body contains C code with statements before declarations.
CODEGEN-1976 Value of __cplusplus is wrong Fixed C6000_8.2.0 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-1967 _swap2 documented as intrinsic in compiler manual but is a macro in c6x.h Fixed C6000_8.2.0 Include the c6x.h header to use the macro, or you can use the intrinsic it is defined to. This is a documentation error. _swap2 is a macro, not an intrinsic. It is defined in c6x.h, which is in the compiler include directory: #define _swap2(src) _packlh2((src), (src))
CODEGEN-1948 _cmplt2 documented as intrinsic in compiler manual but is a macro in c6x.h Fixed C6000_8.2.0 Include the c6x.h header to use the macro, or you can use the intrinsic it is defined to. This is a documentation error. _cmplt2 is a macro, not an intrinsic. It is defined in c6x.h, which is in the compiler include directory: #define _cmplt2(src1, src2) _cmpgt2((src2), (src1))
CODEGEN-1658 SPLOOP Missed Stall Exception with Debugger Fixed C6000_8.2.0 None. A hardware bug on C6000 prevents the debugger from working correctly within certain instruction sequences in an SPLOOP.
CODEGEN-1656 Using --gen_profile_info does not work with -o4 Fixed C6000_8.2.0 C6000_8.2.1 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.
CODEGEN-1639 MISRA-C:2004 17.6/R false positive when assigning local struct member to static struct member Fixed C6000_8.2.0 C6000_8.2.1
SDSCM00051180 Special sections .ovly, .binit, and .TI.crctab missing from EABI spec Fixed C6000_8.2.0
SDSCM00046819 Intrinsic to instruction mapping has typos Fixed C6000_8.2.0
CODEGEN-1517 #pragma FUNCTION_OPTIONS meaningless unless at least -o0 is used Fixed C6000_8.2.0
SDSCM00052878 Documentation error: #pragma pack should be lower case Fixed C6000_8.2.0
CODEGEN-1441 Compiler generates software pipelined loop that has multiple assignment code, and is not interrupt safe Fixed C6000_8.2.0 C6000_8.2.0 If the specific code sequence causing the issue can be located in the assembly source, then a user may insert a DINT instruction in front of the multi-cycle instruction and a RINT instruction after the last delay slot of the multi-cycle instruction. The compiler will mistakenly define and use a register that is defined by a preceeding multi-cycle instruction while the definition of the value created by the multi-cycle instruction is still in the process of being written to that register. If an interrupt occurs between the delay slot definition of that register and the delay slot use of that register, then an incorrect value will arrive in the register for the delay slot use of the register. For example, MPYLI .M1X A4,B6,A5:A4 MVK .S1 2380,A3 || ADD .L1X A3,B8,A5 ADD .L1 A3,A5,A9 LDHU .D1T1 *A9,A5 NOP 1 ... In the above code, if an interrupt occurs in the delay slots of the MPYLI instruction, between the definition of A5 and the subsequent use of A5, then the value in A5 used by the second ADD instruction will be the value that was written to A5 by the MPYLI instruction instead of the first ADD instruction.
CODEGEN-1333 Structure assignment causes compiler to fail with INTERNAL ERROR: Decomposition error Fixed C6000_8.2.0 C6000_8.2.0 Replace struct assignments involving packed structures with a memcpy() call to copy the contents of the RHS of the struct assign to the LHS.
SDSCM00052721 lnk6x automatic RTS selection does not work when thread-safe version of RTS is needed Fixed C6000_8.2.0 C6000_8.2.0 Explicitly specify the thread-safe version of the RTS library that is to be included in the link instead of using libc.a on the link command line or in the linker command file.
SDSCM00008465 INTERNAL ERROR for user code with void pointer dereference Fixed C6000_8.2.2 Don't dereference pointers to type void In relaxed mode, it is possible to write an expression that dereferences a void *. This doesn't mean anything, but if the user's code dereferences a volatile void *, the compiler could crash with an internal error.
