Running all memmove tests in a single function made clang backend crash (`Branch target out of insn range`). It doesn't seem to correlate with a single test. Commenting from test everything after: ``` test___builtin_memmove5_single(48); ``` Makes the test compile and pass. Inverting the selection, and only running `test___builtin_memmove5_single(50);` to `test___builtin_memmove5_single(128);` also makes the test compile & pass. Split `test_builtin_memmove` into two to work-around. Note: Unsure how we can report this to CLANG in a simple repro, given that it seems to be "additive". --- Details: ``` fatal error: error in backend: Branch target out of insn range PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Running all memmove tests in a single function made clang backend crash (`Branch target out of insn range`). It doesn't seem to correlate with a single test. Commenting from test everything after: ``` test___builtin_memmove5_single(48); ``` Makes the test compile and pass. Inverting the selection, and only running `test___builtin_memmove5_single(50);` to `test___builtin_memmove5_single(128);` also makes the test compile & pass. Split `test_builtin_memmove` into two to work-around. Note: Unsure how we can report this to CLANG in a simple repro, given that it seems to be "additive". --- Details: ``` fatal error: error in backend: Branch target out of insn range PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
