* [llvm-objcopy] Improve error message for unrecognised archive memberJames Henderson2019-05-082-6/+51
| | | | | | | | | | | | | | Prior to this patch, llvm-objcopy's error messages for archives with unsupported members only mentioned the archive name, not the member name, making them unhelpful. This change improves it by approximately following GNU objcopy's error message syntax of "<archive name>(<member name>): <problem>".

* [DWARF] Centralize user_id <-> DWARFDIE conversionsPavel Labath2019-05-086-114/+55
| | | | | | | | | | | | | | | | | | | | | | | Summary: The logic for translating a user_id into a DWARFDIE was replicated in several places. This removes that redundancy and settles on a single implementation in SymbolFileDWARF. The reason for choosing that instead of DIERef was that we were always immediately converting the returned DIERef into a DWARFDIE anyway, which meant that one had to specify the SymbolFileDWARF argument twice (once to get the DIERef, and once to get the actual DIE). Also, passing a higher-level object (SymbolFileDWARF) into a lower-level one (DIERef) seemed like a less intuitive arrangement than doing things the other way around.

* [Support] Add error handling to sys::Process::getPageSize().Lang Hames2019-05-0812-22/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return type of sys::Process::getPageSize to Expected<unsigned> to account for the fact that the underlying syscalls used to obtain the page size may fail (see below). For clients who use the page size as an optimization only this patch adds a new method, getPageSizeEstimate, which calls through to getPageSize but discards any error returned and substitues a "reasonable" page size estimate estimate instead. All existing LLVM clients are updated to call getPageSizeEstimate rather than getPageSize. On Unix, sys::Process::getPageSize is implemented in terms of getpagesize or sysconf, depending on which macros are set. The sysconf call is documented to return -1 on failure. On Darwin getpagesize is implemented in terms of sysconf and may also fail (though the manpage documentation does not mention this). These failures have been observed in practice when highly restrictive sandbox permissions have been applied. Without this patch, the result is that getPageSize returns -1, which wreaks havoc on any subsequent code that was assuming a sane page size value. <rdar://problem/41654857> Reviewers: dblaikie, echristo Subscribers: kristina, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D59107 llvm-svn: 360221

| | | | | | | | | | | | | | | | | | | | | | | Summary: A COFF stub indirects the reference to a symbol through memory. A .refptr.$sym global variable pointer is created to refer to $sym. Typically mingw uses these for external global variable declarations, but we can use them for weak function declarations as well. Updates the dso_local classification to add a special case for extern_weak symbols on COFF in both clang and LLVM.
