Always use the string pool, even when it makes the .o larger. This may help tools that read the debug info in the .o files by making the DIE sizes more consistent. llvm-svn: 143186

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location. Differential Revision: https://reviews.llvm.org/D27765 llvm-svn: 290292

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144

Move emission of the debug string table to early in the debug info finalization to greatly reduce the number of fixups that the assembler has to handle in order to improve compile time. llvm-svn: 191119

AsmPrinter: Emit the DwarfStringPool offset directly when possible Change `DwarfStringPool` to calculate byte offsets on-the-fly, and update `DwarfUnit::getLocalString()` to use a `DIEInteger` instead of a `DIEDelta` when Dwarf doesn't use relocations (i.e., Mach-O). This eliminates another call to `EmitLabelDifference()`, and drops memory usage from 865 MB down to 861 MB, around 0.5%. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`; see r236629 for details.) llvm-svn: 238114

Debug Info: instead of calling addToContextOwner which constructs the context after the DIE creation, we construct the context first. This touches creation of namespaces and global variables. The purpose is to handle all DIE creations similarly: constructs the context first, then creates the DIE and immediately adds the DIE to its parent.
