From caefaf781e22a7b053426621719a6f1d0f69d7cb Mon Sep 17 00:00:00 2001 From: Andrew Kelley Date: Sun, 15 Apr 2018 20:15:19 -0400 Subject: std.debug: dumpStackTrace & friends use DirectAllocator this has the downside of failing to print a stack trace when the system is out of memory (maybe we could add a FallbackAllocator which tries DirectAllocator and falls back on the 200KB preallocated buffer). but for the more common use case when the system is not out of memory, but the debug info cannot fit in std.debug.global_allocator, now stack traces will work. this is the case for the self hosted compiler. --- std/debug/index.zig | 25 ++++++++++++++++++++----- 1 file changed, 20 insertions(+), 5 deletions(-) (limited to 'std/debug') diff --git a/std/debug/index.zig b/std/debug/index.zig index a573dc5549..9057f157de 100644 --- a/std/debug/index.zig +++ b/std/debug/index.zig @@ -38,7 +38,7 @@ pub fn getSelfDebugInfo() !&ElfStackTrace { if (self_debug_info) |info| { return info;

Subject: use * for pointer type instead of &

See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
