RUN: a RUN: b || true as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode. Everyone seems to (quite reasonably) write tests assuming the Tcl behavior, so use that in sh mode too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169441 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05Correct ARM NOP encodingDavid Sehr
The encoding of NOP in ARMAsmBackend.cpp is missing a trailing zero, which causes the emission of a coprocessor instruction rather than "mov r0, r0" as indicated in the comment.

2012-12-05Updates to Win64EH.h structures.Michael J. Spencer
Change member types of RuntimeFunction and UnwindInfo from uint64_t to uint32_t: These members represent addresses. According to MSDN, they are image relative, that is, they are 32-bit offsets from the starting address of the image that contains the function table entry. See MSDN for more information: RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx Make Win64.h platform-neutral: The standard types unit8_t, uint16_t and uint32_t are replaced with their counterparts from Endian.h. Accessor functions are introduced to replace bit fields. Patch by João Matos and Kai Nacke. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169414 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05Added a option to the disassembler to print immediates as hex.Kevin Enderby
This is for the lldb team so most of but not all of the values are to be printed as hex with this option. Some small values like the scale in an X86 address were requested to printed in decimal without the leading 0x. There may be some tweaks need to places that may still be in decimal that they want in hex. Specially for arm. I made my best guess. Any tweaks from here should be simple. I also did the best I know now with help from the C++ gurus creating the cleanest formatImm() utility function and containing the changes. But if someone has a better idea to make something cleaner I'm all ears and game for changing the implementation. rdar://8109283 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169393 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05RegisterPressure API. Add support for physical register units.Andrew Trick
At build-time register pressure was always computed in terms of register units. But the compile-time API was expressed in terms of register classes because it was intended for virtual registers (and physical register units weren't yet used anywhere in codegen). Now that the codegen uses physreg units consistently, prepare for tracking register pressure also in terms of live units, not live registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169360 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05docs: Sphinxify `docs/tutorial/`Sean Silva
Sorry for the massive commit, but I just wanted to knock this one down and it is really straightforward. There are still a couple trivial (i.e. not related to the content) things left to fix: - Use of raw HTML links where :doc:`...` and :ref:`...` could be used instead. If you are a newbie and want to help fix this it would make for some good bite-sized patches; more experienced developers should be focusing on adding new content (to this tutorial or elsewhere, but please _do not_ waste your time on formatting when there is such dire need for documentation (see docs/SphinxQuickstartTemplate.rst to get started writing)). - Highlighting of the kaleidoscope code blocks (currently left as bare `::`). I will be working on writing a custom Pygments highlighter for this, mostly as training for maintaining the `llvm` code-block's lexer in-tree. I want to do this because I am extremely unhappy with how it just "gives up" on the slightest deviation from the expected syntax and leaves the whole code-block un-highlighted. More generally I am looking at writing some Sphinx extensions and keeping them in-tree as well, to support common use cases that currently have no good solution (like "monospace text inside a link"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169343 91177308-0d34-0410-b5e6-96231b3b80d8

This change attempts to simplify (X^Y) -> X or Y in the user's context if we know that only bits from X or Y are demanded. A minimized case is provided bellow. This change will simplify "t>>16" into "var1 >>16". ============================================================= unsigned foo (unsigned val1, unsigned val2) { unsigned t = val1 ^ 1234; return (t >> 16) | t; // NOTE: t is used more than once. } ============================================================= Note that if the "t" were used only once, the expression would be finally optimized as well. However, with with this change, the optimization will take place earlier.

2012-12-04Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling
The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange.
