CODEGEN-2010 Decomp error involving packed class Fixed ARM_16.9.0.LTS ARM_16.9.2.LTS Fixed an issue that could result in a "Decomposition error" abort of the compiler.
CODEGEN-1976 Value of __cplusplus is wrong Fixed ARM_16.9.0.LTS ARM_16.9.2.LTS 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-1703 Designated initializer plus struct hack hangs compiler Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS Avoiding using string constants to initialize objects with flexible array members. Instead, use a brace-initialized array. For example: struct { int a; char b[]; } mystruct = {0, {'h', 'e', 'l', 'l', 'o'} }; Fixed a compiler hang caused by initializing flexible array members with string constants. struct {int a; char b[]; } mystruct = {0, "hello"} /* Would cause the compiler to hang and/or crash */
CODEGEN-1640 MISRA 19.1 misreported: #include statements should only be preceded by other preprocessor directives Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS No practical workaround
CODEGEN-1634 MISRA 7.1 misreported: octal tokens in token paste Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS No practical workaround
CODEGEN-1632 MISRA 15.2 misreported: switch clause unconditional break Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS Put an explicit break at the end of the compound statement
CODEGEN-1555 Incorrect result for ullong expression passed to abs Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS Use llabs instead of abs abs(x-y) may compute an incorrect result when x and y are unsigned long long variables.
CODEGEN-1517 #pragma FUNCTION_OPTIONS meaningless unless at least -o0 is used Fixed ARM_16.9.0.LTS
CODEGEN-1429 Software pipelined loop generates different results than loop not pipelined Fixed ARM_16.9.0.LTS ARM_16.9.0.LTS Avoid unsigned expressions in subscripts or in computing subscripts, or compile with -o1 or -o0.
SDSCM00052814 TMS570LC4357 ECC algorithm not supported Fixed ARM_16.9.0.LTS ARM_16.9.1.LTS There is a backdoor in the implementation that you can use to realize this new algorithm. Use this algorithm specification: ECC { algo_name : address_mask = 0xffffffff hamming_mask = /* address */ 0x53aaa750, 0xeb45d688, 0xa6d54da8, 0x9e353c68, 0x7e0cfc18, 0xfe03fc00, 0x01fffc00, 0xfe0003f8, /* upper */ 0x2E4B2E4B, 0x57155715, 0x99A699A6, 0xE338E338, 0xFCC0FCC0, 0x00FF00FF, 0xFF0000FF, 0xFF0000FF, /* lower */ 0xD1B4D1B4, 0x57155715, 0x99A699A6, 0xE338E338, 0xFCC0FCC0, 0x00FF00FF, 0xFF0000FF, 0x00FFFF00, parity_mask = 0x0c mirroring = F021 } If you value your sanity, do not ask where the constants come from. Some devices, such as TMS570LC4357 Hercules, have a FLASH bank in high memory, and ECC uses the high bits of the address in the ECC calculation. Therefore, we need to extend the participating address bits mask in the linker-generated ECC handling.
CODEGEN-1333 Structure assignment causes compiler to fail with INTERNAL ERROR: Decomposition error Fixed ARM_16.9.0.LTS Replace struct assignments involving packed structures with a memcpy() call to copy the contents of the RHS of the struct assign to the LHS.
CODEGEN-1312 RTS header errno.h no longer defines POSIX macros like EFAULT Fixed ARM_16.9.1.LTS
CODEGEN-1287 Compiler and documentation disagree on default for --enum_type Fixed ARM_16.9.0.LTS
SDSCM00040386 Remove -olength option from hex utility's help summary and Users Guides Fixed ARM_16.9.0.LTS ARM_16.9.0.LTS
SDSCM00052902 Assembler incorrectly issues error message: Address must be of a non-global defined in the current section Fixed ARM_16.9.0.LTS The suggested workaround is to go back to 15.12.3.LTS until the next ARM compiler release is available. Alternately, alter the code such that the target label is a non-global symbol defined in the same section as the branch. If the symbol must be global, add a second non-global label such as fake_label and change the branch to "B fake_label".
SDSCM00052734 Internal error in trampoline generation when user defines data symbol named "signal" Fixed ARM_16.9.0.LTS It is a user error to have two different objects in the system with the same name. Rename one of the objects.
SDSCM00051485 Incorrect reordering of nested op= with ++ Fixed ARM_16.9.0.LTS ARM_16.9.0.LTS Don't embed "X op= Y++" under another assignment operator. An expression like "a += b += c++" will produce the wrong answer. The problem is specific to sub-expressions of the form "X op= Y++" that occur under another assignment operator.
