2017-09-14Fix crossgen memory mappings (#13972)Jan Vorlicek3-2/+16
This change removes executable memory mappings from crossgen. Now it can be run on systems with PAX set to prevent executable mappings without any marking using the paxctl.

2017-09-13JIT: mark part of runtime lookup tree as nonfaulting and invariant (#13953)Andy Ayers1-1/+3
An indir in the runtime lookup sequence wasn't marked as nonfaulting so dead context trees could not be entirely cleaned up. Also added invariant since this particular lookup sequence will always return the same result.

2017-09-13Undo more JIT layout workarounds (#13961)Joseph Tremoulet1-25/+19
Remove some `goto`s that were added to work around undesirable jit layout (#9692, fixed in #13314) and epilog factoring (improved in #13792 and #13903), which are no longer needed. Resolves #13466.

2017-09-13Renumber blocks before computing loop nestJoseph Tremoulet4-6/+122
The loop nest computation expects to be able to test block numbers for lexical inclusion, so do a renumbering pass first if blocks have been moved. Fixes #13919.
2017-09-13Fix setting PAX options for crossgen (#13950)Jan Vorlicek2-28/+2
In my previous PR that added marking executables with paxctl, I've made a mistake in the order of calling _add_library and add_dependencies. But that was hidden due to the fact that we have yet another copy of the add_library_clr and add_executable_clr functions in src/CMakeLists.txt. I have no idea how that happened. This one has overriden the other, which has hidden the problem, but also caused the crossgen to not to be modified by the paxctl. So I am fixing the order and removing the extra definitions of those functions.

2017-09-13Disable PAX mprotect for native executables (#13940)Jan Vorlicek2-18/+26
This change adds marking native executables that coreclr build produces (corerun, coreconsole, crossgen, ilasm, ildasm, crashdump) to using the paxctl tool to allow them running on systems with PAX configured so that creating executable memory mappings by applications is prohibited.

2017-09-13Mark Span.Length as non-versionableJan Kotas3-9/+42
This allows inlining Span.Length accross versioning boundaries in R2R images. We are leaking the Span implementation details already because the Span indexer is treated as intrinsic. Marking a few more trivial methods as non-versionable should not do any future harm.

* Introduce FEATURE_GDBJIT_SYMTAB This commit adds new feature FEATURE_GDBJIT_SYMTAB. When it's set ELF file with symtab section will be generated for all JITed methods. It helps lldb and gdb correctly unwind frames of JITed methods as they can use assembly language inspection to determine location of saved registers on stack. * gdbjit symtab feature: use different symbols for each function in JITed code

2017-09-12Re-implemented the ecvt function. (#12894)Jim Ma14-346/+1088
* Re-implemented the ecvt function. Instead of leveraging snprintf, re-implement the ecvt function according to the paper: https://www.cs.indiana.edu/~dyb/pubs/FP-Printing-PLDI96.pdf Note: 1. This commit won't fix any existing bug. 2. This is a raw implementation of the paper. The performance on Linux only gain 10%. We could tune the performance further. Fix #10651 * Resolve a cross platform header file issue. Fix #10651 * Fixed a minor bug. Improved the performance. Fix #10651 * Modified code according to code review feedback. This commit fixed most of the issue found in code review. However, some of the feedback may not be involved due to either little performance improvement or need a POC. Fix #10651 * Try to fix constexpr compile error on Windows. Fix #10651 * Fixed a potential overflow bug in BigNum::Compare. Fix #10651 * Improved multiply 10 operation. Use shift and add operation to replace actual multiply operation. Fix #10651 * Remove old _ecvt function. Fix #10651 * Documented the reason why we do not need m+ and m-. Fix #10651 * Changed exp > 0 to exp != 0 to remove any confusion. exp should fall in 1 ~ 2046 for normalized value. Denormalized value has exp = 0. Fix #10651 * Disable the _ecvt tests. Fix #10651 * Removed _ecvt tests. Fix #10651 * Re-implemented LogBase2. Fix #10651 * Use DWORD and DWORD64 for _BitScanReverse and _BitScanReverse64 Fix #10651 * Fixed x86 compile issue for _BitScanReverse64 x86 does not support _BitScanReverse64 so we have to add additional shift operations to handle it. Fix #10651 * Implemented BitScanReverse64 and BitScanReverse in pal.h Fix #10651 * Remove the confusion comment which is unrelated to BitScanReverse. Fix #10651 * Introduced wmemset to enhance the perf for 0.0 Fix #10651 * Improved the performance of converting 0.0. Fix #10651 * Renamed ecvt to DoubleToNumberWorker. Fix #10651 * Updated code according to the code review feedback. Fix #10651

2017-09-12Fix ARM32 secure delegate bug (#13922)Jan Vorlicek1-1/+16
This change fixes a bug that causes crashes when secure delegate is invoked on ARM32 with legacy codegen. Register R4 was loaded with indirection slot address and immediatelly marked as trashed, so the JIT compiler reused it before the call that was supposed to have that value in R4. The fix was to move the reg trashing after the call. There was also an incorrect marking of that address as EA_PTRSIZE while it should be EA_BYREF, so I've fixed that too.

2017-09-12Remove redundant zero-initialization of struct temps with GC fields. (#13868)Eugene Rozenfeld7-37/+208
Remove redundant zero-initialization of struct temps with GC fields. Structs with GC pointer fields are fully zero-initialized in the prolog if compInitMem is true. Therefore, we don't need to insert zero-initialization for the result of newobj or for inlinee locals when they are structs with GC pointer fields and the basic bock is not in a loop.
