Erik:
Hello,
Please review this patch. A new configure parameter
--enable-native-coverage is introduced. Setting it only works when
using gcc, for now. It adds '-fprofile-arcs -ftest-coverage
-fno-inline' to compiler flags and '-fprofile-arcs' to linker flags,
for both jdk and hotspot native libraries (but not for native test
libraries). Setting this causes gcc to generate code coverage
instrumentation into the binaries as well as generating a .gcno file
for each object file created. The gcno files are needed for
converting gathered coverage data into a comprehensible report. When
native coverage is active, a new image containing the .gcno files is
created by the images target.
