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}.
