| David Fang | b88cdf6 | 2013-08-08 20:14:40 +0000 | [diff] [blame^] | 1 | ; This tests for the basic implementation of PPCMachObjectWriter.cpp, |
| 2 | ; which is responsible for writing mach-o relocation entries for (PIC) |
| 3 | ; PowerPC objects. |
| 4 | ; NOTE: Darwin PPC asm syntax is not yet supported by PPCAsmParser, |
| 5 | ; so this test case uses ELF PPC asm syntax to produce a mach-o object. |
| 6 | ; Once PPCAsmParser supports darwin asm syntax, this test case should |
| 7 | ; be updated accordingly. |
