| 4 | Subject: [PATCH] Altera NIOS2 support |
| 5 | |
| 6 | Add simple nios2 configuration support. |
| 7 | |
| 8 | * include/private/gcconfig.h (NIOS2): New macro. |
| 9 | * include/private/gcconfig.h (mach_type_known, CPP_WORDSZ, MACH_TYPE, |
| 10 | OS_TYPE, DYNAMIC_LOADING, _end, __data_start, DATASTART, DATAEND, |
| 11 | ALIGNMENT, HBLKSIZE, HBLKSIZE, LINUX_STACKBOTTOM, NO_GETCONTEXT): |
| 12 | Define for NIOS2. |
