* land David Blaikie's patch to de-constify Type, with a few tweaks.Chris Lattner2011-07-18
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135375 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a new function attribute, nonlazybind, which inhibits lazy-loadingJohn McCall2011-06-15
| | | | | | | | | | | | | | | | | | optimizations when emitting calls to the function; instead those calls may use faster relocations which require the function to be immediately resolved upon loading the dynamic object featuring the call. This is useful when it is known that the function will be called frequently and pervasively and therefore there is no merit in delaying binding of the function. Currently only implemented for x86-64, where it turns into a call through the global offset table. Patch by Dan Gohman, who assures me that he's going to add LangRef documentation for this once it's committed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133080 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | I kept the reference to the ABI since that is the common case. The -fno-asynchronous-unwind-tables option is a user controlled way of breaking the ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132053 91177308-0d34-0410-b5e6-96231b3b80d8

* Reintroduce the InlineHint function attribute.Jakob Stoklund Olesen2010-02-06
| | | | | | | | | | | | This time it's for real! I am going to hook this up in the frontends as well. The inliner has some experimental heuristics for dealing with the inline hint. When given a -respect-inlinehint option, functions marked with the inline keyword are given a threshold just above the default for -O3. We need some experiments to determine if that is the right thing to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95466 91177308-0d34-0410-b5e6-96231b3b80d8

* Resubmit support for the 'nocapture' attribute.Nick Lewycky2008-12-19
| | | | | | | | | | | The problematic part of this patch is that we were out of attribute bits, requiring some fancy bit hacking to make it fit (by shrinking alignment) without breaking existing users or the file format. This change will require users to rebuild llvm-gcc to match llvm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61239 91177308-0d34-0410-b5e6-96231b3b80d8

* It turns out that "align 1" and unaligned are different. Add a bias to theNick Lewycky2008-12-15
| | | | | | | | | | | alignment attribute such that 0 means unaligned. This will probably require a rebuild of llvm-gcc because of the change to Attributes.h. If you see many test failures on "make check", please rebuild your llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61030 91177308-0d34-0410-b5e6-96231b3b80d8
* Introducing nocapture, a parameter attribute for pointers to indicate that theNick Lewycky2008-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | callee will not introduce any new aliases of that pointer. The attributes had all bits allocated already, so I decided to collapse alignment. Alignment was previously stored as a 16-bit integer from bits 16 to 32 of the attribute, but it was required to be a power of 2. Now it's stored in log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of space. You may have already noticed that you only need four bits to encode a 16-bit power of two, so why five bits? Because the AsmParser accepted 32-bit alignments, even though we couldn't store them (they were silently discarded). Now we can store them in memory, but not in the bitcode. The bitcode format was already storing these as 64-bit VBR integers. So, the bitcode format stays the same, keeping the alignment values stored as 16 bit raw values. There's some hideous code in the reader and writer that deals with this, waiting to be ripped out the moment we run out of bits again and have to replace the parameter attributes table encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61019 91177308-0d34-0410-b5e6-96231b3b80d8
