Re: GCC stack backtraces

If you link with -rdynamic you can show a backtrace with something like the attached code. On Wed, Aug 29, 2012 at 9:22 AM, Ian Lance Taylor wrote: > I've spent the last couple of days working on a stack backtrace library. > > It uses the GCC unwind interface to collect a stack trace, and parses

GCC 4.7.2 Release Candidate available from gcc.gnu.org

The first release candidate for GCC 4.7.2 is available from ftp://gcc.gnu.org/pub/gcc/snapshots/4.7.2-RC-20120914 and shortly its mirrors. It has been generated from SVN revision 191287. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report

GCC 4.7.2 Status Report (2012-09-14), branch frozen

The GCC 4.7 branch is now frozen for creating a first release candidate of the GCC 4.7.2 release. All changes need explicit release manager approval until the final release of GCC 4.7.2 which should happen roughly one week after the release candidate if no issues show up with it. Previous Repor

C++ code in cgraph.h breaking Ada builds?

I added some reference returning member functions in cgraph.h, and now Ada appears to break while including cgraph.h. Huh? gnatbind -nostdinc -I- -I. -Iada -I../../src2/gcc/ada -I../../src2/gcc/ada/gcc-interface -o b_gnat1.adb -n ada/gnat1drv.ali mv b_gnat1.adb b_gnat1.ads ada/ build/gengtype -S

[OT] Control Flow Graph(CFG) into Abstract Syntax Tree(AST)

Hi, I know most compilers go from AST to CFG. I am writing a decompiler, so I was wondering if anyone knew of any documents describing how best to get from CFG to AST. The decompiler project is open source. https://github.com/jcdutton/libbeauty The decompiler already contains a disassembler and a
