2015-02-24readelf: handle corrupted chains betterMike Frysinger1-10/+13
The current chain walker tries to protect itself against loops, by only works with loops of length 1: a chain that points to itself. If you have a chain longer than that (3->4->3->4->...), readelf will still hang. Since we know the max length of the chain, simply abort when we've walked more times than that. The only way that could have happened is if there was a loop.

2015-02-20S390: Support new vector register sectionsAndreas Arnez1-0/+4
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31. Thus a new core file may contain two new register note sections, and this patch adds support to binutils for them. bfd/ * elf-bfd.h (elfcore_write_s390_vxrs_low): Add prototype.
