Illegal instruction error for SSE4 instructions on self-hosting 32-bit build

1

I built valgrind with the following: `./configure --enable-only32bit --enable-inner` and the build succeeded (I'm on macOS 10.14 w/ a 32-bit SDK). However, when I run valgrind on any program, it...

Crash when referencing "--action_env" command line option in settings parameter in transition implementation

7

### Description of the bug: I need to modify the --action_env settings when transitioning, but when I access them in my transition implementation like this ``` ... = settings["//command_line_option:action_env"] ```...

Here's an example, which reports that the memory operand displacement encoding size is 2 bytes, rather than 4: ``` #include #include #include int main() { csh cs; cs_open(CS_ARCH_X86, CS_MODE_64, &cs);...

Remove signed integer overflow from test

1

Remove signed integer overflow from SingleSource/Regression/C/gcc-c-torture/execute/950704-1.c, which invoked undefined behavior. clang at HEAD just compiles this program to a single abort statement (w/ -O3 flag).

incompatible with macOS Catalina 10.15

HaloMD will not run on macOS Catalina, since it uses 32-bit frameworks. How difficult would it be to port the 32-bit components to 64-bit? If it's possible, I'd be willing...

cpu-o3: Clear thread state in time buffers on thread exit

Fix #1049. Clear only thread-specific state from the O3 CPU time buffers, rather than clearing *all* state for *all* threads. Specifically, this patch adds a `clearStates()` method for all O3...

cpu-o3: executing MFENCE in two parallel SMT threads causes hang

3

**Describe the bug** Executing an x86 `mfence` instruction in two sibling SMT threads on the O3 CPU causes the CPU to get stuck. Specifically, it appears that one of the...
