From 91c623d4ee6a9fddf73b8057d61bd9423feeb14d Mon Sep 17 00:00:00 2001 From: David Tweed Date: Fri, 17 May 2013 14:31:59 +0000 Subject: r182085 introduced a change that triggered an assertion on ARM. This is an immediate fix which doesn't resolve the deeper problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182098 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp') diff --git a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp index 57676ffaf4..2773bf1e19 100644 --- a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp +++ b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp @@ -277,6 +277,7 @@ void RuntimeDyldELF::resolveX86Relocation(const SectionEntry &Section, } } +// FIXME: PR16013: this routine needs modification to handle repeated relocations. void RuntimeDyldELF::resolveAArch64Relocation(const SectionEntry &Section, uint64_t Offset, uint64_t Value, @@ -356,6 +357,7 @@ void RuntimeDyldELF::resolveAArch64Relocation(const SectionEntry &Section, } } +// FIXME: PR16013: this routine needs modification to handle repeated relocations. void RuntimeDyldELF::resolveARMRelocation(const SectionEntry &Section, uint64_t Offset, uint32_t Value, @@ -391,8 +393,8 @@ void RuntimeDyldELF::resolveARMRelocation(const SectionEntry &Section, // We are not expecting any other addend in the relocation address. // Using 0x000F0FFF because MOVW has its 16 bit immediate split into 2 // non-contiguous fields. - assert((*TargetPtr & 0x000F0FFF) == 0); Value = Value & 0xFFFF; + *TargetPtr &= ~0x000F0FFF; // Not really right; see FIXME at top. *TargetPtr |= Value & 0xFFF; *TargetPtr |= ((Value >> 12) & 0xF) << 16; break; @@ -402,8 +404,8 @@ void RuntimeDyldELF::resolveARMRelocation(const SectionEntry &Section, case ELF::R_ARM_MOVT_ABS : // We are not expecting any other addend in the relocation address. // Use 0x000F0FFF for the same reason as R_ARM_MOVW_ABS_NC. - assert((*TargetPtr & 0x000F0FFF) == 0); Value = (Value >> 16) & 0xFFFF; + *TargetPtr &= ~0x000F0FFF; // Not really right; see FIXME at top. *TargetPtr |= Value & 0xFFF; *TargetPtr |= ((Value >> 12) & 0xF) << 16; break; -- cgit v1.2.3
