* Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb2007-12-111-6/+10
| | | | | | | | | | | | | | | | | regions of memory that have a target specific relationship, as described in the Embedded C Technical Report. This also implements the 2007-12-11-AddressSpaces test, which demonstrates how address space attributes can be used in LLVM IR. In addition, this patch changes the bitcode signature for stores (in a backwards compatible manner), such that the pointer type, rather than the pointee type, is encoded. This permits type information in the pointer (e.g. address space) to be preserved for stores. LangRef updates are forthcoming. llvm-svn: 44858
* Adding a collector name attribute to Function in the IR. These Gordon Henriksen2007-12-101-10/+23
| | | | | | | | | | | | | | | | | | | | methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. llvm-svn: 44769
* Unbreak backwards compatibility with bytecode format. RegressionChris Lattner2007-11-271-1/+3
| | | | | | | introduced by this patch: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071126/055824.html llvm-svn: 44364

| | | | | | | | | | | | the function type, instead they belong to functions and function calls. This is an updated and slightly corrected version of Reid Spencer's original patch. The only known problem is that auto-upgrading of bitcode files doesn't seem to work properly (see test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully a bitcode guru (who might that be? :) ) will fix it. llvm-svn: 44359
* Next PPC long double bits. First cut at constants.Dale Johannesen2007-10-111-3/+1
| | | | | | | | | No compile-time support for constant operations yet, just format transformations. Make readers and writers work. Split constants into 2 doubles in Legalize. llvm-svn: 42865
* Make temporaries explicit to avoid prematureDale Johannesen2007-09-261-2/+5
| | | | | | destruction of compiler-created ones. llvm-svn: 42383
* Revise previous patch per review comments.Dale Johannesen2007-09-121-5/+2
| | | | | | | Next round of x87 long double stuff. Getting close now, basically works. llvm-svn: 41875
* Add APInt interfaces to APFloat (allows directlyDale Johannesen2007-09-111-6/+13
| | | | | | | | | access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). llvm-svn: 41858

| | | | llvm-svn: 41769
* Next round of APFloat changes.Dale Johannesen2007-09-061-2/+3
| | | | | | | | | | | | | | Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) llvm-svn: 41747
* Patch 10 for long double. Doing constants right needs expanding ConstantFPDale Johannesen2007-08-091-3/+9
| | | | | | | | | | | | to handle values bigger than double. If we assume host==target and host long double works correctly, this is not too bad, but we don't want to have that limitation longterm. I could implement accepting double constants as long double or something like that, which would lead to incorrect codegen with no errors; the more I think about that the worse it seems. Rather than do such a hack that would be backed out later, I'm settling for giving reasonable error messages, for now. llvm-svn: 40974
