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 |

C6000_8.2.0 |
C6000_8.2.1 |

| 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. |
