      Move hashmap into src/base. · 2fd55667
      lpy authored 
      We ported hashmap.h into libsampler as a workaround before, so the main focus of
this patch is to reduce code duplication. This patch moves the hashmap into
src/base as well as creates DefaultAllocationPolicy using malloc and free.

      S390: Implemented ALCR in S390 simulator. · 8760b602
      bryleun authored 
      This CL implements the ALCR, add logical 32-bit integer with carry, instruction in the s390 simulator.

Some 64-bit operations in the 4-byte arithmetic section of the s390 simulator have been refactored into a separate function to stay below 500 lines.

      S390: Fixed s390 simulation check for underflow in subtraction. · 0d24a0fc
      bryleun authored 
      Clang optimizes away CheckOverflowForIntSub at any opt
level (includes -O1, -O2, -O3) into a false statement,
resulting in incorrect values being returned. As the C++
standard considers overflows to be undefined behaviour,
this is technically correct as compilers can assume that
overflows never occur, but problematic in our case (where
overflows do occur, and a specific result is expected).

This change replaces the original check with a call to a
function that is optimized in a manner that returns correct output.

      S390: Fixed condition code handling on FP->INT and FP rounding in simulator. · 2fdc0ae3
      bryleun authored 
      The below instructions were fixed so that the produced condition
codes in simulator matched behaviour in native s390 CPUs:

CFDBR
CGDBR
CGEBR
CFEBR
CLFDBR
CLGDBR
CLGEBR

Also implemented the CLFEBR instruction in s390 simulator.

(Copypaste of 1763663003, which was pointing at wrong branch - should be master, not lkgr)

      PPC64: [turbofan] Changed TruncateFloat64ToInt64 to TryTruncateFloat64ToInt64. · b9f92c15
      mbrandy authored 
      Port 95844d94

Original commit message:
    The new operator provides a second output which indicates whether the
    conversion from float64 to int64 was successful or not. The second
    output returns 0 if the conversion fails. If the conversion succeeds,
    then the second output is differs from 0.

    The second output can be ignored, which means that the operator can be
    used the same way as the original operator.

      PPC: Make Simulator respect C stack limits as well. · bcc9df92
      mbrandy authored 
      Port 7fb31bdb

Original commit message:
    The simulator uses a separate JS stack, exhaustion of the C stack
    however is not caught by JS limit checks. This change now lowers the
    limit of the JS stack accordingly on function calls.

      Fixed various simulator-related space leaks. · 84aa494e
      svenpanne authored 
      Alas, this involved quite a bit of copy-n-paste between the
architectures, but this is caused by the very convoluted
relationships, lifetimes and distribution of responsibilities. This
should really be cleaned up by moving code around and using STL maps,
but that's not really a priority right now.

Bonus: Fixed leaks in the ARM64 disassembler tests.

      Contribution of PowerPC port (continuation of 422063005) - PPC dir update · 308d913a
      michael_dawson authored 
      Contribution of PowerPC port (continuation of 422063005, 817143002 and 866843003)
This patch brings the ppc directories up to date with our repo. We have
removed 5 individual optimizations which require changes in both the ppc and common
directories so they can be more easily reviewed on their own in subsequent patches.

Subsequent patches will cover:
- individual optimizations for PPC (5)
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
for AIX)
- incremental updates required to ppc directories due to platform specific changes
made in google repos while we complete the above steps.

With the update there are still some timeouts seen when run in simulated mode which
may be a result of the missing optimizations.  Once we have the optimizations in
we will review the simulation results and address/exclude tests as necessary so that
the simulated runs are clean.
