From 3fca788967bb3fd37675bfb177d38ff8e8e2c920 Mon Sep 17 00:00:00 2001 From: Renato Golin Date: Wed, 29 Jan 2014 11:50:56 +0000 Subject: Enable EHABI by default After all hard work to implement the EHABI and with the test-suite passing, it's time to turn it on by default and allow users to disable it as a work-around while we fix the eventual bugs that show up. This commit also remove the -arm-enable-ehabi-descriptors, since we want the tables to be printed every time the EHABI is turned on for non-Darwin ARM targets. Although MCJIT EHABI is not working yet (needs linking with the right libraries), this commit also fixes some relocations on MCJIT regarding the EH tables/lib calls, and update some tests to avoid using EH tables when none are needed. The EH tests in the test-suite that were previously disabled on ARM now pass with these changes, so a follow-up commit on the test-suite will re-enable them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200388 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp') diff --git a/lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp b/lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp index b2a71a8706..5cb6c0b44e 100644 --- a/lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp +++ b/lib/Target/ARM/MCTargetDesc/ARMMCAsmInfo.cpp @@ -16,9 +16,11 @@ using namespace llvm; +// ARM EHABI is experimental but the quality is good enough +// to be turned on by default on non-Darwin ARM targets. cl::opt -EnableARMEHABI("arm-enable-ehabi", cl::Hidden, - cl::desc("Generate ARM EHABI tables"), +DisableARMEHABI("arm-disable-ehabi", cl::Hidden, + cl::desc("Disable ARM experimental exception handling"), cl::init(false)); @@ -52,7 +54,7 @@ ARMELFMCAsmInfo::ARMELFMCAsmInfo() { SupportsDebugInformation = true; // Exceptions handling - if (EnableARMEHABI) + if (!DisableARMEHABI) ExceptionsType = ExceptionHandling::ARM; // foo(plt) instead of foo@plt -- cgit v1.2.3
