| 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-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. |
| 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. |
