patch 9.0.2186: LTCG compile error ARM64 for write_chars Commit: https://github.com/vim/vim/commit/38bea30f53da8e4a8847407404597b255b20334e Author: Saleem Abdulrasool <compnerd@compnerd.org> Date: Wed Dec 27 18:57:12 2023 +0100 patch 9.0.2186: LTCG compile error ARM64 for write_chars Problem: LTCG compile error on Win/ARM64 for `write_chars()` Solution: Explicitly initialise the storage to use data rather than BSS (Saleem Abdulrasool) win32: add a workaround for a LTCG issue on Windows ARM64 It appears that the implicit initialisation which would push `g_coords` into BSS causes an aliasing issue with LTCG on ARM64. By explicitly initialising the value, we use usual data storage but prevent the aliasing. This allows the console version of VIM to run on Windows ARM64 again. fixes: #13453 closes: #13775 Signed-off-by: Saleem Abdulrasool <compnerd@compnerd.org> Signed-off-by: Christian Brabandt <cb@256bit.org>
