Lu <hjl.tools@gmail.com> commit 8eb2510d38226ce10a3a15109be948f052585106 Author: Florian Weimer <fweimer@redhat.com> Date: Mon Jan 17 09:57:19 2022 +0100 elf: Set l_contiguous to 1 for the main map in more cases l_contiguous was not initialized at all for the main map and always 0. This commit adds code to check if the LOAD segments are adjacent to each other, and sets l_contiguous accordingly. This helps _dl_find_object because it is more efficient if the main mapping is contiguous. Note that not all (PIE or non-PIE) binaries are contiguous in this way because BFD ld creates executables with LOAD holes: ELF LOAD segments creating holes in the process image on GNU/Linux https://sourceware.org/pipermail/binutils/2022-January/119082.html https://sourceware.org/bugzilla/show_bug.cgi?id=28743 Reviewed-by: H.J.
