* dwarf2out.c (comp_dir_string): cached_wd could be set to both a

ggc the gc string might get reused and corrupted. Fixed by always

[doc] Fix typos in MINLOC, MAXLOC documentation

I think there's a typo in the documentation of the MINLOC and MAXLOC intrinsics.
It implies that when the BACK argument is true it returns the first occurrence of the min/max value,
but my understanding is that it should return the last occurrence.

This patch fixes the documentation.

* intrinsic.texi (MINLOC): Fix typo in BACK argument documentation.
(MAXLOC): Likewise.

rs6000: Make CSE'ing __tls_get_addr calls possible

CSE does not consider calls, not even const calls. This patch puts a
REG_EQUAL note on the pseudo we assign the __tls_get_addr result to,
so that those pseudos can be CSE'd and the extra calls deleted as dead
code.

CSE should really handle const calls directly, but it is stage 4.


* config/rs6000/rs6000.c (rs6000_legitimize_tls_address): Add REG_EQUAL
notes for the result of the __tls_get_addr calls.
