Re: [ANNOUNCE] GHC 8.2.1 release candidate 1

Hi Ben, it sounds like some of the remaining limitations around DWARF support (e.g. finishing the stack sampling work, local bindings in GDB, ...) could make for a good Haskell Summer of Code project. Have you considered writing this up as one or two project ideas here:

Hi Ben, thank you for this summary. The DWARF status page is helpful. Something was unclear to me though. There are three main potential use cases for DWARF that I see: 1. debugging, possibly with gdb 2. stack traces on exceptions 3. stack sampling, which is a form of performance profiling.

Hi Ben, The windows build is unusable. The settings file has $TopDir expanded and hard-coded to the build path on drydock. Tamar On Mon, 10 Apr 2017, 08:14 Boespflug, Mathieu, wrote: > Hi Ben, > > this is great news! I'm particularly keen on learning more about two > points you

Hi Ben, this is great news! I'm particularly keen on learning more about two points you mentioned in your email: * Compiler performance: do you have any numbers to quantify what 8.0 vs 8.2 is likely to look like? How much has the work that's been done affect performance across the board? Or are
