| 4 | Subject: What is test/Libraries? |
| 5 | |
| 6 | Hey everyone, |
| 7 | |
| 8 | There has recently been some confusion over what test/Libraries is and |
| 9 | what it is used for. The short answer is: it's used when building GCC, |
| 10 | not for tests, so you all shouldn't need to use it. |
| 11 | |
| 12 | test/Libraries contains the LLVM "system libraries", which are linked to |
| 13 | programs when the linker is run with the appropriate -l switch (for |
| 14 | example -lm links in the "math" library). In general, these libraries are |
| 15 | just stubbed out libraries, because noone has had the time to do a full |
| 16 | glibc port to LLVM. |
| 17 | |
| 18 | Problems arise because the makefiles have a number of hardcoded paths in |
| 19 | it that are used to copy files around and install the libraries, which |
| 20 | cause problems if anyone (except for me) uses them. I'm sorry a better |
| 21 | system isn't in place yet for these libraries, but if you just ignore |
| 22 | them, they won't cause you any harm. :) |
