Ok, so I thought it was all well and good, but now a bug report made me |
| 10 |
realise that gcc < 3.4 doesn't have -fpie/-fno-pie. |
| 11 |
|
| 12 |
Here's the problem: |
| 13 |
1) valgrind has some features that only work with -fpie |
| 14 |
2) valgrind's tests fail to build with -fpie |
| 15 |
3) because of the hardened gcc profile, valgrind's tests need -fno-pie |
| 16 |
4) simply patching some makefiles to add -fno-pie for tests is not |
| 17 |
possible because gcc < 3.4 doesn't support -fno-pie |
| 18 |
5) having the valgrind developers modify their configure/makefiles to |
| 19 |
add -fno-pie for tests in case gcc supports it is not enough, because |
| 20 |
user CFLAGS are appended and CFLAGS in make.conf may contain -fpie |
| 21 |
6) using filter-flags to get rid of -fpie in user's CFLAGS actually |
| 22 |
adds -fno-pie and disables features referred to in 1) |
| 23 |
|
| 24 |
What do I do now? |
| 25 |
|
| 26 |
Why is -fno-pie being added by filter-flags anyway? |
| 27 |
