To get a good error message for all files that could contain Mach-O

where the error come from a Mach-O file in an archive or a universal file.

Most of this is fixed by moving the call to checkSymbolTable() into
ProcessMachO() and calling it when the operation needs the symbol
table.  And then calling the form of report_error() that has the
ArchiveName and ArchitectureName arguments.  One other place
needed to call this form of report_error() also with these arguments.

Also changed the code in MachODump.cpp to not use report_fatal_error()
and use report_error() instead to make the code smaller and cleaner.  All
cases of this are for errors with the symbol table which should now never
be tripped since checkSymbolTable() should be called first to get a good

7 years agoAdd .clang-format to libc++
Eric Fiselier [Tue, 15 Nov 2016 20:21:30 +0000 (20:21 +0000)]
Add .clang-format to libc++

Adding a Clang Format file to libc++ and which style it should use has been
discussed a couple of times. This patch finally adds a .clang-format file
which specifies LLVM styles.

Personally I dislike how the LLVM style handles much of the meta-programming
in libc++. However the general consensus was that libc++ should prefer the
LLVM style and make adjustments where needed.

Note that using clang-format on changes is not required, especially for
changes within the headers. However formatting tests should be encouraged.
