sys-libs/compiler-rt: Override start symbol when adding -nostartfiles to LDFLAGS |
| 9 |
|
| 10 |
Trying to link executables for the configure checks generates linker |
| 11 |
warnings (in the CMake logs) like: "warning: cannot find entry symbol |
| 12 |
_start; defaulting to 0000000000001000". |
| 13 |
Moreover, with flags like -flto or -Wl,--gc-sections, the linker can |
| 14 |
discard all code, rendering the checks useless. |
| 15 |
|
| 16 |
Set main as entry symbol when linking with -nostartfiles to avoid |
| 17 |
both issues. (Note that the binaries would still crash, but that |
| 18 |
doesn't matter since they are never executed.) |
