In -mrelax mode, GCC/Clang may generate a local-exec TLS code sequence like: ``` # R_RISCV_TPREL_HI20, R_RISCV_RELAX lui rd, %tprel_hi(x) # R_RISCV_TPREL_ADD, R_RISCV_RELAX add rd, rd, tp, %tprel_add(x) # (R_RISCV_TPREL_LO12_I || R_RISCV_TPREL_LO12_S), R_RISCV_RELAX addi rd, rd, %tprel_lo(x) || sw rs, %tprel(x)(rd) ``` Note: st_value(x) for TLS should be in the range [0,p_memsz(PT_TLS)). When st_value(x) < 2048 (i.e. hi20(x) == 0), the linker can relax the code sequence to: ``` addi rd, tp, st_value(x) || sw rs, st_value(x)(rd) ``` Differential Revision: https://reviews.llvm.org/D129425 |

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
