From f316727e5f6a4c58b63bdee9ad6be785f97f5ee7 Mon Sep 17 00:00:00 2001 From: Iain Buclaw Date: Fri, 19 Nov 2021 14:43:07 +0100 Subject: libphobos: Increase size of defaultStackPages on OSX X86_64 targets. As of macOS 11, libunwind now requires more stack space than 16k, so default to a larger stack size. This is only applied to X86 as the PAGESIZE is still 4k, however on AArch64 it is 16k. libphobos/ChangeLog: * libdruntime/core/thread/fiber.d (defaultStackPages): Increase size on OSX X86_64 targets. --- libphobos/libdruntime/core/thread/fiber.d | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'libphobos') diff --git a/libphobos/libdruntime/core/thread/fiber.d b/libphobos/libdruntime/core/thread/fiber.d index f4c04ce..2f90f17 100644 --- a/libphobos/libdruntime/core/thread/fiber.d +++ b/libphobos/libdruntime/core/thread/fiber.d @@ -595,6 +595,16 @@ class Fiber // the existence of debug symbols and other conditions.
