See https://lists.llvm.org/pipermail/llvm-dev/2020-July/143373.html "[llvm-dev] Multiple documents in one test file" for some discussions. `extract part filename` splits the input file into multiple parts separated by regex `^(.|//)--- ` and extract the specified part to stdout or the output file (if specified). Use case A (organizing input of different formats (e.g. linker script+assembly) in one file). ``` // RUN: extract lds %s -o %t.lds // RUN: extract asm %s -o %t.s // RUN: llvm-mc %t.s -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. ``` Use case B (for utilities which don't have built-in input splitting feature): ``` // RUN: extract case1 %s | llc | FileCheck %s --check-prefix=CASE1 // RUN: extract case2 %s | llc | FileCheck %s --check-prefix=CASE2 Combing tests prudently can improve readability. This is sometimes better than having multiple test files. ``` Since this is a new utility, there is no git history concerns for UpperCase variable names. I use lowerCase variable names like mlir/lld.
