Nick Terrell e3bda594ae Prefer __builtin_prefetch over inline asm 
Reorder the ifdefs for the PREFETCH macros so that the compiler builtin is
favored over the inline assembly for aarch64.

W. Felix Handte c1449143c5 Share stat() Calls in Uses of UTIL_chmod() 2020-08-05 12:10:42 -04:00
W. Felix Handte 0a8aacb4db Use stat() to Check that File Should be chmod()-ed 
Rather than special-casing a check for `/dev/null`, this uses `stat()` to
avoid `chmod()`-ing any non-regular file. I believe this is the desirable
behavior. `UTIL_chmod()` is never called on directories at the moment, only
output files.

W. Felix Handte 7238cca1a1 Deduplicate Some Low-Hanging Fruit of Redundant Stat Calls 2020-08-05 01:08:34 -04:00
W. Felix Handte 44fa052599 Introduce Variants of Various UTIL Functions that Take Pre-Populated stat_t Structs 
Instead of calling `stat()`, these functions accept the result of a previous
`stat()` call on the file in question, which will allow us to make multiple
decisions around a file without redundant `stat()` calls.

W. Felix Handte b6e24bc4dc Rename UTIL_getFileStat() -> UTIL_statFile() and UTIL_getDirectoryStat() -> UTIL_statDir() 
I want to introduce versions of many of these functions that take pre-
populated `stat_t` objects and use those rather than doing their own redundant
`stat()` internally. These functions will have `...Stat()` suffixes. So this
commit renames these existing functions into the active voice, to avoid
confusion.
