Summary: * Revise the patch for relocatable NLS support. * Code size benchmark analysis.

Details: 1. Revise the patch for relocatable NLS support: lp:918926. * Read the gcc configure and makefile. * It seams hard to get the relative dir if the gcc is configured with --bindir=... --datadir/datarootdir. E.g. --bindir=/opt/bin --datarootdir=/tmp/data 2. Code size benchmark analysis with -Os * Investigate regression in small cases. 3. Try to build linaro gcc trunk with crosstool-ng. But it reports error when configuring libquadmath. * configure:9829: error: Link tests are not allowed after GCC_NO_EXECUTABLES. * Manual check or a simple case show libc.so can be linked.

Plans: * Tuning optimization heuristics for -Os

Planed leaves: * April 9 - 11: Vacations
