* Make x86-64 stack walking work for Native Client minidumpsmseaborn@chromium.org2013-05-082-4/+16
| | | | | | | | | | | | | | For NaCl, a stack walker should ignore the top 32 bits of %rip, %rsp and %rbp, otherwise it will try to read from %r15-extended stack addresses and look up symbol info for %r15-extended code addresses, which will fail.

Looking at p_offset for this isn't correct, and the first segment doesn't have p_offset == 0 here because NaCl can't map the ELF file headers as part of the first segment (which is for validatable code only).

* Add explicit OMAP support to dump_syms.chrisha@chromium.org2013-05-0123-14147/+20051
| | | | | | | | | | | | | | This CL adds new utilities to common/windows for handling OMAP information in PDB files. It then augments PdbSourceLineWriter with explicit OMAP knowledge so that symbolization will proceed more cleanly for images whose PDB files contain OMAP information. This makes breakpad handle OMAPped symbol files as cleanly as WinDbg.

* Improve ARM CPU info reporting.digit@chromium.org2013-04-2415-127/+1249
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves several things for Linux/ARM: - Better detection of the number of CPUs on the target device. The content of /proc/cpuinfo only matches the number of "online" CPUs, which varies over time with recent Android devices. - Reconstruct the CPUID and ELF hwcaps values from /proc/cpuinfo, this is useful to better identify target devices in minidumps. - Make minidump_dump display the new information in useful ways. - Write a small helper class to parse /proc/cpuinfo and also use it for x86/64. - Write a small helper class to parse sysfds cpu lists. - Add a my_memchr() implementation. - Add unit tests. Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs) and a Nexus 4 (4 CPUs).
