This is a list of currently open issues for the TASKING VX-toolset for RISC-V v1.2r1. The list may include issues found in later releases, whether such issues also appear in this releasehas not always been verified yet. See below for the list of closed issues. The list of fixed issues for v1.2r1 is included in the release notes of the product.
| ID | Summary |
| RISCV-104 | Storing 24-bit structures may overwrite 32 bits of memory |
| RISCV-106 | Option --tune=arcv-rhx100 produces incorrect code |
| RISCV-113 | Option --tune=arcv-rhx100 produces incorrect code |
| RISCV-142 | Compiler produces incorrect code for a vararg function when parameter is a struct |
| RISCV-155 | C compiler criscv ignores __attribute__(( section("...") )) and __section__("...") |
| RISCV-167 | Incorrect code generated for 64-bit multiply by constant when using --tune=arcv-rhx100 |
| RISCV-170 | C compiler mis-evaluates inline chained relational/bitwise comparison on unsigned char, computing wrong boolean result |
| RISCV-171 | Potentially wrong results from R_RISCV_PCREL_LO12_I and R_RISCV_PCREL_LO12_S relocation functions |
| RISCV-176 | Incorrect handling of large struct variadic arguments |
| RISCV-180 | Using linker symbols may lead to duplicate global symbols with different values |
| RISCV-183 | CRC recognition is not precise enough |
| RISCV-184 | Widening conversion after addition with constant might lose wraparound behavior |
| RISCV-185 | Option -Av is not always honored |
| RISCV-186 | Linker does not update DWARF values when relaxation is enabled |
| RISCV-187 | Linker can remove a lui for higher bits that was still used during relaxation optimization |
| RISCV-194 | Statement expressions can crash the compiler or produce wrong code |
| RISCV-197 | Early return and conditional call at function end may corrupt caller's stack |
| RISCV-206 | Sequenced stores to a volatile object are combined into a single unconditional write |
| RISCV-209 | Interrupt handlers do not save and restore vector registers |
| RISCV-210 | std::exception_ptr comparison and rethrow_exception give incorrect results |
| RISCV-211 | Compression of prologues and epilogues with run-time library routines breaks interrupt handlers |
| RISCV-216 | Miscompilation for always-false range checks |
| RISCV-218 | Floating-point literal parser mis-rounds an exact round-to-nearest-even tie |
This is a list of issues that have been closed with a resolution other than fixed. This list contains issues that will not be fixed, issues that appeared to be not a problem and/or issues that could not be reproduced. The list of fixed issues for v1.2r1 is not shown here, it is included in the release notes of the product.
