James Henderson	b7a90ef48e	[ELF] Fail the link early if the map file path is invalid ... As with the changes made in r297645, we do not want a potentially long link to be run, if it will ultimately fail because the map file is not writable. This change reuses the same functionality as the output file path check. See https://reviews.llvm.org/D30449 for further justification and explanations.

Rui Ueyama	fed8b570b7	Make FileOutputBuffer fail early if you pass a directory. ... Previously, it created a temporary directory and then failed when FileOutputBuffer tried to rename that file to the destination file (which is actually a directory name).

Rui Ueyama	eaeca5ed79	[ELF] Fail the link early if an output path is invalid ... Patch from James Henderson. If a user has a long link, e.g. due to a large LTO link, they do not wish to run it and find that it failed because there was a mistake in their command-line, after they waited for some significant amount of time. This change adds some basic checking of the linker output file path, which is run shortly after parsing the command-line and linker script. An error is emitted if LLD cannot write to the specified path. Differential Revision: https://reviews.llvm.org/D30449 llvm-svn: 297645	2017-03-13 17:24:52 +00:00
