--HG-- extra : convert_revision : 566841577bf4a98cac0b65292fe0f7daf89a9203
2007-08-04X86: Make 64 bit unaligned accesses work as well as the other sizes.Gabe Black
There is a fundemental flaw in how unaligned accesses are supported, but this is still an improvement. --HG-- extra : convert_revision : 1c20b524ac24cd4a812c876b067495ee6a7ae29f
2007-08-04X86: Make the open flags correct.Gabe Black
--HG-- extra : convert_revision : 2dc81345176d1de247a567d1f748e2b2bd05f829
2007-08-04X86: Make fixed register operands ignore register index extensions from the ↵Gabe Black
REX prefix. The only cases where this was the correct behavior are now handled with the "B" operand type, and doing things this way was breaking some instructions, notably a shift. --HG-- extra : convert_revision : 072346d4f541edaceba7aecc26ba8d2cd756e481

2007-08-04X86: Start implementing segmentation support.Gabe Black
Make instructions observe segment prefixes, default segment rules, segment base addresses. Also fix some microcode and add sib and riprel "keywords" to the x86 specialization of the microassembler. --HG-- extra : convert_revision : be5a3b33d33f243ed6e1ad63faea8495e46d0ac9
2007-08-04X86: Create a base enum value for indexing into a region of the miscregs.Gabe Black
This lets you index into a group of registers without having to know explicitly which one is the lowest in that group. --HG-- extra : convert_revision : e3cad25a1c5910955204c37177b049ca9834cfd9
2007-08-04X86: Add the arch_prctl system call and fix up some microcoding.Gabe Black
The arch_prctl system call is used to set and get the FS and GS segment bases. The FS segment is use for TLS, so glibc needs to be able to set it up. --HG-- extra : convert_revision : 79501491a15967a7a862add846ff88a934fb1b37

2007-08-02X86: Finally get the x86 initial stack frame right.Gabe Black
After very carefully reading through the Linux source, I'm pretty confident I now know -exactly- how the initial stack frame is constructed, filled, and aligned. --HG-- extra : convert_revision : 3c654ade7e458bdd5445026860f11175f383a65f

2007-08-01Arguments: Get rid of duplicate code for the Arguments class in each ↵Ali Saidi
architecture. Move the argument files to src/sim and add a utility.cc file with a function getArguments() that returns the given argument in the architecture specific fashion. getArguments() was getArg() is the architecture specific Argument class and has had all magic numbers replaced with meaningful constants. Also add a function to the Argument class for testing if an argument is NULL. --HG-- rename : src/arch/alpha/arguments.cc => src/sim/arguments.cc rename : src/arch/alpha/arguments.hh => src/sim/arguments.hh extra : convert_revision : 8b93667bafaa03b52aadb64d669adfe835266b8e
2007-08-01MIPS: Cleaned up includes to break loops, and got rid of isa_traits.ccGabe Black
Loops of header files including each other was causing compilation to fail. To fix it, a bunch of unnecessary includes were removed, and the code in isa_traits.cc which brought a bunch of include chains together was broken up and put in proximity to the header files that delcared it. --HG-- extra : convert_revision : 66ef7762024b72bb91147a5589a0779e279521e0

2007-08-01X86: Get rid of initialization of R11Gabe Black
R11 is just junk after the start of exectuion because we're "returning" from an execve call and linux destroys the contents of rcx and r11 on system calls. --HG-- extra : convert_revision : 6bf69a50ce56e0355dfdd41524163874340beec0

2007-07-31X86: Add operand type information to the fnstcw and fldw instruction ↵Gabe Black
placeholders. These are the only floating point instructions that get used in my simple hello world test. These instructions are for setting up the floating point control register. Their not being implemented doesn't affect anything because floating point isn't used. --HG-- extra : convert_revision : 4dfb9ef2a5665f034946c504978029e8799e64cd
