New Revision: 240322
URL: http://llvm.org/viewvc/llvm-project?rev=240322&view=rev
Log:
Use C99 to compile ISL
ISL with small integer optimization requires C99 to compile. gcc < 5.0
still uses C89 as default, so we need to enable the options to compile
in C99 mode.
This patch is preparing the actual activation of small integer
optimization.
