Commit Message

Bill Fischofer Aug. 27, 2016, 11:49 p.m. UTC 
Add support for the --enable-shared=[yes|no] configure options.
--enable-shared=yes is the default and results in suppressing the use
of inlines for ODP API functions to enhance ABI compatibility at
potentially some performance cost. When --enable-shared=no is specified,
inlines are allowed to boost performance at the possible loss of ABI
compatibility.

This patch addresses Bug https://bugs.linaro.org/show_bug.cgi?id=2490

Note: This patch is a port of the corresponding enhancements made to
odp-dpdk with a few changes, mainly that inlines are now part of the
odp/api/plat directory, and all ODP APIs are now treated uniformly with
regard to whether inlining is permitted.
