branch libiberty-pic updated: last-svn-commit-566-ge222518

by git＠lrde.epita.fr

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "Olena, a generic and efficient image processing platform". The branch libiberty-pic has been updated discards 07fe77d332c3f965bc1b787bda765f5b2fbe2341 (commit) discards c23c47928224c69eeadc539f85400749495706a0 (commit) discards d3cd1aa0a318cd998d6da9a2c13e9c5831116ed6 (commit) discards 45f7112e908c9e32cf6a0f33ead120ff0c53b63f (commit) discards de87f38439ee6a1d61806244caf726a5c8e9d368 (commit) discards cf101e3de813d028e91b9224fc275d97bd6d73d7 (commit) discards c1521eb5c4e1e5d92a5ddeab2c1960a0a9bc5626 (commit) via e22251860ebb2ed0691abaeb10a60cbdf899802a (commit) via 72191f7881ca5da0df2d0a0be82b8f75a99bfcb0 (commit) via 1712587063361e777e99cc2dc0e9e69c55a76295 (commit) via 3f96f84fc087b6bde1b39b1d1c9823a92d953123 (commit) via 913844fe64a7ab1328f75c6ba4362aac80503e64 (commit) via 0117b205ee9b11bc7b5b34e9ffbdc0520969becc (commit) via 92c53da51d7fabb2573fbe93634d5c1cec105365 (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (07fe77d332c3f965bc1b787bda765f5b2fbe2341) \ N -- N -- N (e22251860ebb2ed0691abaeb10a60cbdf899802a) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- e222518 Build Libiberty as a shared library. 72191f7 Mention Libiberty in Extatica's AUTHORS, NEWS and README. 1712587 Work around a defect in Libiberty's `configure.ac' (in Olena). 3f96f84 Work around a defect in Libiberty's `configure.ac' (in Extatica). 913844f Fix the distribution of Libiberty. 0117b20 Fix cleaning rules in Libiberty. 92c53da Make Libiberty compatible with Automake. ----------------------------------------------------------------------- Summary of changes: extatica/ChangeLog | 2 ++ extatica/libiberty/Makefile.in | 2 +- extatica/libiberty/local.mk | 2 +- 3 files changed, 4 insertions(+), 2 deletions(-) hooks/post-receive -- Olena, a generic and efficient image processing platform
