--- Comment #1 from Fangrui Song <i at maskray dot me> --- >From https://maskray.me/blog/2021-08-08-toolchain-testing#split-file In Aug 2020, I added `split-file` to llvm-project which allows you to place multiple extra files in one file. It'd be nice if binutils has something similar. Use case A (organizing input of different formats (e.g. linker script+assembly) in one file). ```text # RUN: split-file %s %t # RUN: llvm-mc %t/asm -o %t.o # RUN: ld.lld -T %t/lds %t.o -o %t This is sometimes better than the %S/Inputs/ approach because the user can see the auxiliary files immediately and don't have to open another file. # asm ... # lds ... ``` Use case B (for utilities which don't have built-in input splitting feature): ```text // RUN: split-file %s %t // RUN: llc < %t/1.ll | FileCheck %s --check-prefix=CASE1 // RUN: llc < %t/2.ll | FileCheck %s --check-prefix=CASE2 Combing tests prudently can improve readability. For example, when testing parsing errors if the recovery mechanism isn't possible, grouping the tests in one file can more readily see test coverage/strategy. //--- 1.ll ... //--- 2.ll ... ``` -- You are receiving this mail because: You are on the CC list for the bug.
