; REQUIRES: x86

; Test to make sure the thinlto-object-suffix-replace option is handled
; correctly.

; Generate bitcode file with summary, as well as a minimized bitcode without
; the debug metadata for the thin link.
; RUN: opt --thinlto-bc %s -thin-link-bitcode-file=%t1.thinlink.bc -o %t1.o

; First perform the thin link on the normal bitcode file, and save the
; resulting index.
; RUN: ld.lld --plugin-opt=thinlto-index-only -shared %t1.o -o %t3
; RUN: cp %t1.o.thinlto.bc %t1.o.thinlto.bc.orig

; Next perform the thin link on the minimized bitcode file, and compare dump
; of the resulting index to the above dump to ensure they are identical.
; RUN: rm -f %t1.o.thinlto.bc
; Make sure it isn't inadvertently using the regular bitcode file.
; RUN: rm -f %t1.o
; RUN: ld.lld --plugin-opt=thinlto-index-only \
; RUN: --plugin-opt=thinlto-object-suffix-replace=".thinlink.bc;.o" \
; RUN: -shared %t1.thinlink.bc -o %t3
; RUN: diff %t1.o.thinlto.bc.orig %t1.o.thinlto.bc
; Also check that this works without the --plugin-opt= prefix.

; RUN: -shared %t1.thinlink.bc -o %t3

; Ensure lld generates error if object suffix replace option does not have 'old;new' format

; RUN: -o %t3 2>&1 | FileCheck %s --check-prefix=ERR1
; ERR1: --plugin-opt=thinlto-object-suffix-replace= expects 'old;new' format, but got abc:def

; If filename does not end with old suffix, no suffix change should occur,
; so ".thinlto.bc" will simply be appended to the input file name.
