## Test the --symtab-file option to specify a separate file for the symbol table.
## We create two ELF files: one with DWARF debug info (but no function symbols)
## and one with function symbols (but no DWARF). Then we use --symtab-file to
## combine them during GSYM conversion.

# RUN: split-file %s %t

## Create the debug-only and symtab-only ELF files.
# RUN: yaml2obj %t/debug.yaml -o %t/debug.elf
# RUN: yaml2obj %t/symtab.yaml -o %t/symtab.elf

## Test 1: Basic --symtab-file usage.
# RUN: llvm-gsymutil --convert %t/debug.elf --symtab-file=%t/symtab.elf -o %t/out.gsym 2>&1 | FileCheck %s --check-prefix=BASIC
# BASIC: Input file: {{.*}}debug.elf
# BASIC: Output file (x86_64): {{.*}}out.gsym
# BASIC: Using symbol table file: {{.*}}symtab.elf
# BASIC: Loaded 2 functions from symbol table.

## Test 2: Architecture mismatch error.
# RUN: yaml2obj %t/aarch64-symtab.yaml -o %t/aarch64-symtab.elf
# RUN: not llvm-gsymutil --convert %t/debug.elf --symtab-file=%t/aarch64-symtab.elf -o %t/mismatch.gsym 2>&1 | FileCheck %s --check-prefix=MISMATCH
# MISMATCH: architecture mismatch: input file is x86_64 but symbol table file '{{.*}}aarch64-symtab.elf' is aarch64

## Test 3: Invalid symtab file error.
# RUN: not llvm-gsymutil --convert %t/debug.elf --symtab-file=%t/debug.yaml -o %t/invalid.gsym 2>&1 | FileCheck %s --check-prefix=INVALID
# INVALID: The file was not recognized as a valid object file
