patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll' Commit: https://github.com/vim/vim/commit/02fcae02a926e4e8379d77fb716da4202029882d Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Wed Feb 21 19:40:44 2024 +0100 patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll' Problem: infinite loop in win_update with 'smoothscroll' set when window width is equal to textoff, or signed integer overflow if smaller. Solution: don't revalidate wp->w_skipcol in that case, as no buffer text is being shown. (Sean Dewar) Don't instead reset w_skipcol; that would lose the scroll position within the line, which may be undesirable if the window is made wider later. Also include changes from the splitmove PR #14042 that I (in my infinite Git wisdom) forgot to commit. This includes a change to Test_window_split_no_room to ensure it doesn't fail for some screen sizes. Move Test_smoothscroll_in_zero_width_window to test_scroll_opt.vim, as that file feels more appropriate. closes: #14068 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>

INSTALLami.txt - Installation of Vim from source on Amiga and MorphOS

This file contains instructions for compiling Vim. If you already have an
executable version of Vim, you don't need this.

The file "feature.h" can be edited to match your preferences. You can skip
this, then you will get the default behavior as is documented, which should
be fine for most people.

Summary:
make -f Make_ami.mak        gcc
make -f Make_ami.mak CC=vc  vbcc

Please note that currently only gcc has been tested. VBCC would need its own
CFLAGS, but should otherwise work out of the box. For cross-compiling, UNM
can be used to override uname and thereby set the target. An example is shown
below:

make -f Make_ami.mak CC=ppc-morphos-gcc UNM=MorphOS
