...unoptimized code, since they will cause the debugger's single-stepping to behave unpredictably, thus destroying the debugging experience. In optimized code, the expectations are a bit lower, but *incorrect* debug locations are terrible since they will cause misleading crash traces and otherwise undebuggable code. Due to the nature of what an optimizing compiler does, debug information is not always salvageable, but the correct thing to do in this case is to remove the debug information (e.g., by inserting line: 0 locations) instead of providing incorrect or partially correct information. > &g...

Please don't do this to get the underlying vector length (or to achieve anything else). Setting/deleting attributes of an R object without checking the reference count violates R semantics, which in turn can have unpredictable results on R programs (essentially undebuggable segfaults now or more likely later when new optimizations or features are added to the language). Setting attributes on objects with reference count (currently NAMED value) greater than 0 (in some special cases 1 is ok) is cheating - please see Writing R Extensions - and getting speedups v...

Hi, (Resent with proper subject line) I recently found myself in trouble because the crash I had disappeared with -g, so I could not debug the program. This happened because the optimizer did not remember to consider DBG_VALUEs instruction so it changed its behavior, and the bug went hiding. I then started discussing this onhttps://reviews.llvm.org/D45878, and

I didn't really feel comfy with their use of mod_rewrite which is pretty much undebuggable and black magic, but used a CGI script instead. It at least currently seems to work well enough that we're not completely horked in terms of existing URLs, but if someone finds a URL that doesn't work, I'll hammer on it. -hpa

I had used WineTools to install IE6 under WINE 0.9.something (0.9.4, I think). It worked fine to connect to my employer's Citrix server and run Citrix apps that required 128-bit encryption to run SSL connections. Since updating WINE to 0.9.6 (via Apt-get, I run Debian), whenever I try to connect to the Citrix server, I get a message informing me that 128-bit encryption is required and I

I tested the program SkyGlobe 3.6 listed as Platinum in the following AppDB page: http://appdb.winehq.org/objectManager.php?sClass=application&iId=5143 The program failed to start in Wine 1.0-rc1. The following is the output from the console: $ wine skyglobe.exe fixme:ddraw:VGA_ioport_out Unsupported index, register 0x3ce: 0x08 (value 0xff) fixme:ddraw:VGA_ioport_out Unsupported index,

Is there a low-level function that returns the length of an object 'x' - the length that for instance .subset(x) and .subset2(x) see? An obvious candidate would be to use: .length <- function(x) length(unclass(x)) However, I'm concerned that calling unclass(x) may trigger an expensive copy internally in some cases. Is that concern unfounded? Thxs, Henrik

I’m River and I’m a compiler engineer at PlayStation. Recently, I’ve been working on an interprocedural outlining (code folding) pass for code size improvement at the IR level. We hit a couple of use cases that the current code size solutions didn’t handle well enough. Outlining is one of the avenues that seemed potentially beneficial. -- Algorithmic Approach -- The general implementation can be
