From: David Blaikie Date: Thu, 3 Apr 2014 06:28:20 +0000 (+0000) Subject: DebugInfo: Use a 64 bit type for the subrange X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=1233d41ff47cc29aaa36e45d2afd6b68899efbef;p=oota-llvm.git DebugInfo: Use a 64 bit type for the subrange While we were encoding 64 bit values (data8) in the subrange itself, using a 32 bit type for the subrange was still confusing the gdb. Oh, and make it unsigned too. As the comment points out, this could be pushed into the frontend so that it would be 32 or 64 bit as appropriate, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205512 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/CodeGen/AsmPrinter/DwarfUnit.cpp b/lib/CodeGen/AsmPrinter/DwarfUnit.cpp index 97f251086ae..82e9bb008a0 100644 --- a/lib/CodeGen/AsmPrinter/DwarfUnit.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfUnit.cpp @@ -1766,12 +1766,12 @@ void DwarfUnit::constructArrayTypeDIE(DIE &Buffer, DICompositeType CTy) { // as different languages may have different sizes for indexes.
