Back when the command-line reference rst was in-tree, a lot of people missed the "DO NOT EDIT" comment at the top, and then changes were effectively reverted when the file was regenerated. I went through the changes, and rescued the interesting bits of documentation that were destroyed. (Noticed when I was trying to find our documentation for -fno-delete-null-pointer-checks, but it was missing.)
- I'm intentionally leaving out D73459 because I'm not sure how to port the changes to -march.
- Some options have help text in Options.td, but that text doesn't make it into the reference. Incomplete list of such options: -fc++-static-destructors, -frtti-data, -fplt, -fstrict-return, -funique-section-names, -fuse-init-array. I think there's something specifically weird with boolean options, but not completely sure what's happening.
