Subject: [wwwdocs] gcc-5/changes.html: Graphite - CLooG removal; Fortran - update
Date: Wed, 12 Nov 2014 10:54:00 -0000 [thread overview]
Message-ID: <20141112105247.GC27434@physik.fu-berlin.de> (raw)

Hi all, hi Gerald, hi Tobias and Roman,
the patch updates gcc-5/changes.html; the Fortran bits are obvious.
For CLooG:
* That CLooG is no longer needed is the main reason for writing this
Caveat item.
* Regarding ISL 0.12.2: The recommended version already changed
2014-02-13 and thus for 4.9 (cf. PR59878); gcc-4.8/changes.html
had 0.11.1 - and gcc-4.9/changes.html doesn't mention ISL or CLooG.
I don't know whether the GCC 5 change of using ISL directly instead
of CLooG with ISL backend causes an explicit requirement of ISL 0.12.2,
but not using 0.11.x is definitely a good idea.
* It is planned to additionally support ISL 0.14.0 (which fixes
PR62289) - but which is API incompatile to ISL 0.12.2. Whence that
patch is in, one has to re-write this item.
OK? Comments? Suggestions?
* * *
BTW: There is currently no version check in configure for ISL, maybe one
should add one for include/isl/stdint.h, which defines:
#define _GENERATED_STDINT_H "isl 0.12.2"
For the in-tree build, one could check isl/GIT_HEAD_ID or
isl/configure{,.ac}.
Tobias
