Requests, cd commands, df commands ... all hang ... for as long as three HOURS and they cannot be killed (kill -1, -15, -9) and the smb cannot be restarted. Presumably this is all a result of the calls being hung within the kernel. It has been suggested that we upgrade...

...o do full decoding of eh_frame records to remove garbage. Paul is right there will be code size overhead. Eh_frame is usually created per a compilation module with common information in CFI. Multiple eh_frames will cause a lot of redundant CFI. There might be a case when the total size of redundant CFIs will be greater than the total size of removed garbage. As I wrote in the previous message, I don't think there's a size issue in link results because even existing linkers merge CIEs by contents. -------------- next part -------------- An HTML attachment was scrubbed...

...ponse buffer Stats also shows: 2156 session 1688 share reconnects One box finally gave up. I could not get apache to let go of the cifs mounts. When I did a shutdown the box hung and I had to do a power cycle. I switched the second box back to smbfs and now the first box is again happily running cfis. Any hints above how I can get both boxes to talk to the Win2000 server at the same time? The WIN2000 event logs didn't pick up any errors. Thanks, Joe Edwards UW Libraries

I'm a bit confused by this subthread -- doesn't BOLT have the exact same CFI bloat issue? From my cursory reading of the propellor doc, the CFI duplication is _necessary_ to represent discontiguous functions, not anything particular to the way Propellor happens to generate those discontiguous functions. And emitting discontiguous functions is a fundamental goal of this, right? On Wed,

I haven''t had a chance to work on fixing multiple controller view paths recently. My original patch attempt was: http://dev.rubyonrails.org/ticket/8582 It was rejected due to the fact that it was fixing the symptom more than the problem. However, I think it''s critical that this problem get fixed, otherwise the whole concept of view_paths is severely neutered and

No I haven't. Thank you for the pointer. Looks like the problem of the inverted edges was discussed there. But I guess my bigger question is this: why do we still create one big .eh_frame even if -ffunction-sections is given? When the option is given, Clang creates .text, .rela.text and .gcc_exception_table sections for each function, but it still creates a monolithic .eh_frame that covers

Greetings, We, at Google, recently evaluated Facebook’s BOLT, a Post Link Optimizer framework, on large google benchmarks and noticed that it improves key performance metrics of these benchmarks by 2% to 6%, which is pretty impressive as this is over and above a baseline binaryalready heavily optimized with ThinLTO + PGO. Furthermore, BOLT is also able to improve the performance of binaries
