| 1 | pmbaty | 1 | // QNX 8.0 linker driver by Pierre-Marie Baty <pm@pmbaty.com> |
| 2 | |||
| 3 | // RATIONALE |
||
| 4 | // until a proper QNXToolchain class is implemented in the Clang driver, Clang relies on GNU GCC to drive the system linker 'ld'. |
||
| 5 | // So we *HAVE* to provide a 'gcc' executable for Clang to be able to link QNX files. |
||
| 6 | // GNU GCC is itself a driver which can also invoke a compiler or a linker (gcc invokes collect2 which in turn invokes ld). |
||
| 7 | // This means our GCC will need to either chain-call 'clang' when it is called for *compiling* and chain-call 'ld' when it is called for *linking*. |
||
| 8 | // When proper support is added to it, GNU GCC contains a linker specification for the system which it uses to construct the linker command line. |
||
| 9 | // The linker specifications for QNX 8.0 can be extracted from '<target triple>-gcc -dumpspecs' and have been reimplemented in this file. |
||
| 10 | // The GNU specs language is documented here: https://gcc.gnu.org/onlinedocs/gcc/Spec-Files.html |
