| ## Test how obj2yaml emits relocation addend descriptions. |
| ## We document that relocation addends are dumped as signed int64 decimal values. |
| |
| ## Case 1: Check a 64-bit object. |
| |
| ## Check how obj2yaml dumps an addend with an arbitrary positive value. |
| ## We use 1 as it is the first possible positive value. |
| # RUN: yaml2obj --docnum=1 %s -o %t1 -D ADDEND=1 |
| # RUN: obj2yaml %t1 | FileCheck %s --check-prefix=ELF64 --match-full-lines -DADDEND=1 |
| |
| # ELF64: Relocations: |
| # ELF64-NEXT: - Symbol: foo |
| # ELF64-NEXT: Type: R_X86_64_PC32 |
| # ELF64-NEXT: Addend: [[ADDEND]] |
| |
| ## Check how obj2yaml dumps an addend with an arbitrary negative value. |
| ## We use -1 as it is the first possible negative value. |
| # RUN: yaml2obj --docnum=1 %s -o %t2 -D ADDEND=-1 |
| # RUN: obj2yaml %t2 | FileCheck %s --check-prefix=ELF64 --match-full-lines -DADDEND=-1 |

| ## Check how obj2yaml dumps an addend with the value INT64_MAX. |

| # RUN: obj2yaml %t3 | FileCheck %s --check-prefix=ELF64 --match-full-lines -DADDEND=9223372036854775807 |
| |
| ## Check how obj2yaml dumps an addend with the value INT64_MIN. |
| # RUN: yaml2obj --docnum=1 %s -o %t4 -D ADDEND=-9223372036854775808 |
| # RUN: obj2yaml %t4 | FileCheck %s --check-prefix=ELF64 --match-full-lines -DADDEND=-9223372036854775808 |
