| ## This is a regression test which makes sure that when there is an invalid section index |
| ## associated with a section symbol, the linker does not segfault. |
| |
| ## Test YAML content was created using the following steps |
| ## 1. Create an object file from the following assembly |
| ## `llvm-mc -filetype=obj -triple=arm64-apple-darwin symbol.s -o symbol.o` |
| ## |
| ## .text |
| ## .section __TEST,__mystuff |
| ## .globl _mysec |
| ## _mysec: |
| ## .byte 0xC3 |
| ## |
| ## 2. Use obj2yaml to convert object file to yaml |
| ## `obj2yaml symbol.o -o symbol.yaml` |
| ## |
| ## 3. Manually set n_sect value of ltmp1 symbol to 10 which is greater than the number of sections 2. |
| ## |
| |
| # RUN: yaml2obj %s -o %t |
| # RUN: not %lld -platform_version macos 10.14 11.0 -arch arm64 %t 2>&1 | FileCheck %s --check-prefix=FATAL |
| |
| # FATAL: error: section symbol ltmp0 in {{.*}} has an invalid section index [10] greater than the total number of sections [2] |
