From f9ff65d4dffbaf342dce7a8760059c27683cd962 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 8 Oct 2020 10:27:43 +1030 Subject: [GOLD] Increase --split-stack-adjust-size For functions with small (< 256 bytes) stack frames, the current x86 do_calls_non_split ignores --split-stack-adjust-size and, in combination with __morestack_non_split, supplies a non-split-stack function with at least 0x100000 (1M) available stack. On powerpc64, a default of 0x4000 is not large enough to reliably work with the golang testsuite. This increase the default size to the defacto x86 value. * options.h (split_stack_adjust_size): Default to 0x100000. --- gold/ChangeLog | 4 ++++ gold/options.h | 2 +- 2 files changed, 5 insertions(+), 1 deletion(-) (limited to 'gold') diff --git a/gold/ChangeLog b/gold/ChangeLog index 5a1b03b..fd9fc63 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,3 +1,7 @@ +2020-10-08 Alan Modra + + * options.h (split_stack_adjust_size): Default to 0x100000. + 2020-09-26 Alan Modra * powerpc.cc (Target_powerpc): Rename power10_stubs_ to diff --git a/gold/options.h b/gold/options.h index bc21115..51d3614 100644 --- a/gold/options.h +++ b/gold/options.h @@ -1260,7 +1260,7 @@ class General_options "output sections"), N_("(PowerPC only) Each output section has its own stubs")); - DEFINE_uint(split_stack_adjust_size, options::TWO_DASHES, '\0', 0x4000, + DEFINE_uint(split_stack_adjust_size, options::TWO_DASHES, '\0', 0x100000, N_("Stack size when -fsplit-stack function calls non-split"), N_("SIZE")); -- cgit v1.1
