Hi, I'm trying to write a pass for LTO, and now I want to debug it using gdb. I use ld as my target file, but when I run the program in gdb, it reports [Thread debugging using libthread_db enabled] Cannot find new threads: generic error at Plugin::load() { #ifdef ENABLE_PLUGINS this->handle_ = dlopen(this->filename_.c_str(), RTLD_NOW); in binutil/src/gold/plugin.cc The gdb version is 7.0.1. I tried it with other multi-threaded programs without any problem. Have I missed something? Or I shouldn't debug my pass this way at all? btw, "llvm-gcc -use-gold-plugin" works f...

I think this is my last round of patches for issues I identified with the retry filter. With this in place, it should be safe to interject another filter in between retry and the plugin. Eric Blake (5): retry: Don't call into closed plugin tests: Refactor test-retry-reopen-fail.sh tests: Enhance retry test to cover failed reopen server: Move prepare/finalize/close recursion to

Since v1: - patch 1: check size limits - patch 2: better handling of default export name canonicalization - patch 3: support filters as well as plugins - patch 4: new - patch 5: rewrite sh parser, fix testsuite to actually work and cover more cases (now that libnbd.git is fixed) Eric Blake (4): server: Add exports list functions server: Prepare to use export list from plugin log: Add
