--- Begin Message ---Subject: simplify and tune Emacs stack-related allocation Date: Thu, 7 Jun 2018 19:27:52 -0700 While looking into the Emacs garbage collector's stack-overflow problems I noticed several opportunities for improving performance and simplifying the code in minor ways. I plan to install the attached patches to take advantage of these opportunities; although they don't address stack overflow, they can be thought of as a first, cleanup step toward addressing stack overflow. User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Thunderbird/52.8.0 Overall these patches trim about 250 lines from the C source code, and should improve efficiency by not creating objects on the heap to handle stack-related events such as implementing save-excursion. This patch also removes primitives like 'free_misc' that ask for trouble by second-guessing the garbage collector. I'm filing this as a bug report in order to give the patches a bit of time to cool before installing. Comments welcome, as usual.0001-New-mint_ptr-representation-for-C-pointers.patch
