* [lldb] [cmake] Fix installing Python modules on systems using /usr/libMichal Gorny2019-09-252-10/+13
| | | | | | | | | | | | | | | Fix installing Python modules on systems that use /usr/lib for Python while installing other libraries in /usr/lib64. Rewrite CMake logic to query correct directories from Python, similarly to how prepare_binding_Python.py does it. Furthermore, change the regex used in get_relative_lib_dir.py to allow 'lib' without suffix. I think that the code can be further improved but I'd like to take this enterprise in smaller steps in case one of them breaks something.

* [AArch64] Convert neon_ushl and neon_sshl with positive constants to VSHL.Florian Hahn2019-09-252-45/+49
| | | | | | | | | | | | | | | | | | I think we should be able to use shl instead of sshl and ushl for positive constant shift values, unless I am missing something. We already have the machinery in place to ensure we only replace nodes, if the shift value is positive and <= the element width. This is a generalization of an earlier patch rL372565.

* [ELF] Add -z separate-loadable-segments to complement separate-code and ↵Fangrui Song2019-09-256-14/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | noseparate-code D64906 allows PT_LOAD to have overlapping p_offset ranges. In the default R RX RW RW layout + -z noseparate-code case, we do not tail pad segments when transiting to another segment. This can save at most 3*maxPageSize bytes. a) Before D64906, we tail pad R, RX and the first RW. b) With -z separate-code, we tail pad R and RX, but not the first RW (RELRO). In some cases, b) saves one file page. In some cases, b) wastes one virtual memory page. The waste is a concern on Fuchsia. Because it uses compressed binaries, it doesn't benefit from the saved file page. This patch adds -z separate-loadable-segments to restore the behavior before D64906. It can affect section addresses and can thus be used as a debugging mechanism (see PR43214 and ld.so partition bug in crbug.com/998712).

* [CMake] Copy over the system debugserver when using LLDB_USE_SYSTEM_DEBUGSERVERJonas Devlieghere2019-09-247-5/+13
| | | | | | | | | | | | | | | | r366433 broke support for the system debugserver. Although the change was well-intended, it (presumably) unintentionally removed the logic to copy over the debugserver. As a result, even with LLDB_USE_SYSTEM_DEBUGSERVER enabled, we ended up building, signing and using the just-built debugserver. This patch partially recovers the old behavior: when LLDB_USE_SYSTEM_DEBUGSERVER is set we don't build debugserver and just copy over the system one.

* [BPF] Generate array dimension size properly for zero-size elementsYonghong Song2019-09-242-27/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if an array element type size is 0, the number of array elements will be set to 0, regardless of what user specified. This implementation is done in the beginning where BTF is mostly used to calculate the member offset. For example, struct s {}; struct s1 { int b; struct s a[2]; }; struct s1 s1; The BTF will have struct "s1" member "a" with element count 0. Now BTF types are used for compile-once and run-everywhere relocations and we need more precise type representation for type comparison. Andrii reported the issue as there are differences between original structure and BTF-generated structure. This patch made the change to correctly assign "2" as the number elements of member "a". Some dead codes related to ElemSize compuation are also removed. Differential Revision: https://reviews.llvm.org/D67979 llvm-svn: 372785
