| 1 | | If hardware lacks basic or specialized functionality, compiler-rt adds such functionality |
| 2 | | for basic arithmetic(s). |
| 3 | | One such example is 64-bit integer multiplication on 32-bit x86. |
| 4 | | |
| 5 | | Goals: |
| 6 | | 1. zig as linker for object files produced by other compilers |
| 7 | | => `function compatibility` to compiler-rt and libgcc for same-named functions |
| 8 | | * compatibility conflict between compiler-rt and libgcc: prefer compiler-rt |
| 9 | | 2. `symbol-level compatibility` low-priority compared to emitted calls by llvm |
| 10 | | * symbol-level compatibility: libgcc even lower priority |
| 11 | | 3. add zig-specific language runtime features, see #7265 |
| 12 | | * example: arbitrary bit width integer arithmetic |
| 13 | | * lower to call those functions for e.g. multiplying two i12345 numbers together |
| 14 | | * proper naming + documention for standardizing (allow languages to follow our exmaple) |
| 15 | | |
| 16 | | Current status (tracking libgcc documentation): |
| 17 | | - Integer library routines => almost implemented |
| 18 | | - Soft float library routines => finished |
| 19 | | - Decimal float library routines => unimplemented (~120 functions) |
| 20 | | - Fixed-point fractional library routines => unimplemented (~300 functions) |
| 21 | | - Exception handling routines => unclear, if supported (~32+x undocumented functions) |
| 22 | | - Miscellaneous routines => unclear, if supported (cache control and stack function) |
| 23 | | - No zig-specific language runtime features in compiler-rt yet |
| 24 | | |
| 25 | | This library is automatically built as-needed for the compilation target and |
| 26 | | then statically linked and therefore is a transparent dependency for the |
| 27 | | programmer. |
| 28 | | For details see `../compiler_rt.zig`. |
| 29 | | |
| 30 | | Bugs should be solved by trying to duplicate the bug upstream, if possible. |
| 31 | | * If the bug exists upstream, get it fixed upstream and port the fix downstream to Zig. |
| 32 | | * If the bug only exists in Zig, use the corresponding C code and debug |
| 33 | | both implementations side by side to figure out what is wrong. |

| 791 | | [^PSRZC]: return result in the CPSR Z and C flag. C is clear only if the |
| 792 | | operands are ordered and the first operand is less than the second. |
| 793 | | Z is set only when the operands are ordered and equal. |
| 794 | | Preserves all core registers except ip, lr, and the CPSR. |
