It does with pcregrep -M. For example,
$ pcregrep -M 'sprintf\s*\(\s*([^,]*)\s*,\s*"%s[^"]*"\s*,\s*\1\s*,' \
linux-2.6/arch/x86/kernel/cpu/intel_cacheinfo.c
ret += sprintf(buf, "%sEntry: %d\n", buf, i);
ret += sprintf(buf, "%sReads: %s\tNew Entries: %s\n",
buf,
ret += sprintf(buf, "%sSubCache: %x\tIndex: %x\n",
buf, (reg & 0x30000) >> 16, reg & 0xfff);
However, it appears that the multiline results did not show up in Kees’
reports, so the reports should be rerun with pcregrep -M if that is
possible.
