;; This test is similar to llvm/test/ThinLTO/X86/selective-save-temps.ll
; REQUIRES: x86
; UNSUPPORTED: system-windows
;; Unsupported on Windows due to difficulty with escaping "opt" across platforms.
;; lit substitutes 'opt' with /path/to/opt.
; RUN: rm -rf %t && mkdir %t && cd %t
; RUN: mkdir all all2 all3 build subset subset2 && cd build
; RUN: opt -thinlto-bc -o main.o %s

;; with the output from individualized save-temps later
; RUN: ld.lld main.o thin1.o --save-temps -o %t/all/a.out

;; Run linker and generate files
;; Make sure a.out exists and is correct (by diff-ing)
;; this is the only file that should recur between runs
;; (Also, for some stages, copy the generated files to %t/subset2 to check composability later)
;; Move files that were expected to be generated to %t/all3
;; Make sure there's no unexpected extra files
