This adds [f]getc() and fgets() for parsing config files. Probably hard to avoid. Still trying to decide if I actually want to add system() or not. -hpa

The PE headers of the generated efi file were quite buggy. And since OVMF perform a few consistency checks, syslinux was unable to run on it. I don't pretend to have a thorough understanding of the PE+ headers, some bugs may remain. :) Celelibi (4): efi: Fix PE header field rva_and_sizes_nr efi: Location, size and alignment of .text section efi: Useless relocations in PE file efi: PE

This is a small series getting rid of paravirt patching by switching completely to alternative patching for the same functionality. The basic idea is to add the capability to switch from indirect to direct calls via a special alternative patching option. This removes _some_ of the paravirt macro maze, but most of it needs to stay due to the need of hiding the call instructions from the compiler

Michael, I have rework the patch according to your suggestion. And I have read binutil/objdump source code and found that it has a logic that if there's no symtab, it will use dynsym, which is missing in llvm-objdump.

Hello, all experts. When I use pid provider, my Dscript with -F option output the codepath with flowindent as you know, e.g. -> main -> f1 -> f2 however I realized that the exec file I used at that time was stripped. Does anyone know the reason why I could see the function names? Thanks in advance. -- This message posted from opensolaris.org
