CODEGEN-5387 Custom version of scanf fails when --opt_for_speed=3 is used Open C2000_18.9.0.STS
CODEGEN-5317 Ternary (?:) expression with 0/1 result uses type of predicate, not result, when optimised Planned C2000_18.9.0.STS C2000_18.9.0.STS
CODEGEN-5231 Object file display (OFD) utility displays wrong offset for DW_AT_type entries Accepted C2000_18.9.0.STS
CODEGEN-4960 Using --gen_profile_info with code with CLA source fails to build Open C2000_18.9.0.STS N/A. As the title says, when using the --gen_profile_info option with a project that contains CLA code, it fails with an invalid filename as shown in the error message below:>> Compilation failure recipe for target 'matrix_mpy.obj' failed fatal error: Error opening icode file "C:\\Users\\user\\AppData\\Local Temp {B38860D0-28F1-4B19-9A99-2F0EA95 A0EA8} ":>> Abort - Cannot open input icode file C:\\Users\\user\\AppData\\Local\\Temp\\\\ {B38860D0-28F1-4B19-9A99-2F0EA95A0EA8} p: No such file or directory This does not happen with F28x projects that are free of CLA code. This was reproduced in CCSv8.1.0 with the default C2000 compiler version 18.1.2
CODEGEN-4895 For enum type variables incorrectly issue diagnostic: comparison between signed and unsigned operands Open C2000_18.9.0.STS The user can work around this by introducing a dummy enumeration constant with a negative value, as below. This causes the enum to have signed underlying type, which will get rid of the warning: enum E { zero = 0, one = 1, dummy = -1 }; Given this code: enum E { zero = 0, one = 1 }; int f(__typeof__(one) a, enum E b) { return a > b; } You will get this remark: remark: comparison between signed and unsigned operands This is technically not a bug. When you declare an enum, the underlying type might be signed or unsigned, but the standard explicitly says that "An identifier declared as an enumeration constant has type int" (C99 Thus, __typeof__(one) is "int", despite the fact that E has an unsigned underlying type.
CODEGEN-4885 See MISRA diagnostics when compiling stdio.h Accepted C2000_18.9.0.STS
CODEGEN-4712 Inconsistent application of MISRA rule 10.1 The value of an expression of integer type shall not be implicitly converted Accepted C2000_18.9.0.STS
CODEGEN-4617 Compiler incorrectly issues MISRA 12.6 diagnostic: Expressions that are effectively Boolean should not be used Accepted C2000_18.9.0.STS
CODEGEN-4342 cerr.tie() returns the wrong value Open C2000_18.9.0.STS
SDSCM00051392 C2000 float software multiply doesn't handle -1*INF properly Accepted C2000_18.9.0.STS
SDSCM00051384 C2000 can't print 0 with %a format Accepted C2000_18.9.0.STS
SDSCM00050131 Local struct with non-constant initializer treated as static scope variable Accepted C2000_18.9.0.STS
SDSCM00049280 Ill advised enum scalar usage gets MISRA diagnostic, but similar usage of enum array does not Open C2000_18.9.0.STS
SDSCM00049278 Array that is correctly initialized erroneously gets a MISRA diagnostic about size not being specified Open C2000_18.9.0.STS
SDSCM00046113 C2000 RTS float arithmetic functions do not round correctly Open C2000_18.9.0.STS
SDSCM00040934 Structure is not initialized correctly when using -o2 or -o3 optimization Accepted C2000_18.9.0.STS The initialization will have to be done at run-time, through a __sti initialization routine. You can see this routine when compiling without optimization. To workaround the compiler removing this initialization routine, initialize the object at the beginning of main: Info2.mSize = ((unsigned)_end_isr_stack - (unsigned)_start_isr_stack);
SDSCM00018691 Linker gives misleading warning when dot expressions used in SECTION directive for .stack section Accepted C2000_18.9.0.STS
SDSCM00016646 strcmp doesn't correctly handle values with uppermost bit set Accepted C2000_18.9.0.STS
SDSCM00008928 Extern inline functions are not supported in the C/C++ Compiler with COFF ABI Accepted C2000_18.9.0.STS This bug only affects COFF ABI. If a function is declared as inline and there are no references to it in the same file, the function is eliminated and can't be called from another file.
SDSCM00008685 DWARF does not correctly represent variables stored in register pairs Planned C2000_18.9.0.STS Although 'var1' and 'var2' are shown to be in single registers, a debugger could determine that they are actually stored in register pairs by looking at the type of the variables: [00000113] DW_TAG_base_type DW_AT_name long long DW_AT_encoding 0x5 DW_AT_byte_size 0x8 The base type indicates that the size of the variables is 0x8 bytes. Since a single register can only store 0x4 bytes of information, it would take two registers to hold this values. On TI architectures, values stored in multiple registers are always stored in consecutive registers. Thus, the debugger would know that if the entire value could not fit in A4, the rest of the value must be in A5. A5 would contain the upper 32 bits of the value.
SDSCM00008652 pow(2,x) has fairly significant rounding error Accepted C2000_18.9.0.STS Please describe the workaround for this problem.
SDSCM00008630 printf gives wrong value for pointer when its value is incremented Open C2000_18.9.0.STS To get rid of the warning message modify the printf statement as follows: printf('0x%lx\n', 0x10000 + (t=(long int)&global_var)); This modified code executes correctly too.
SDSCM00008543 Forward reference in .space generates an internal error Accepted C2000_18.9.0.STS none
SDSCM00008248 Compilers on PC will not work without TMP set Accepted C2000_18.9.0.STS Set the TMP environment variable, even if just set to . (current directory)
