5 years agoAdd lvIsImplicitByRef information to lvaSetStruct (#19223)
Jarret Shook [Wed, 17 Apr 2019 18:06:16 +0000 (11:06 -0700)]
Add lvIsImplicitByRef information to lvaSetStruct (#19223)

Before implicit byrefs were tracked by setting lvIsParam and lvIsTemp.
This change explicitly adds a flag for implicitByRef instead of overloading.
In addition, it fixes the decision to copy an implicitByRef for arm64 varargs.

Temporarily bump weight on byref params to match old behavior and avoid codegen
diffs.

Re-enabled various tests and parts of tests.

Closes #20046
Closes #19860

Fix x86 stack probing (#23881)

* Fix x86 stack probing

On x86, structs are passed by value on the stack. We copy structs
to the stack in various ways, but one way is to first subtract the
size of the struct and then use a "rep movsb" instruction. If the
struct we are passing is sufficiently large, this can cause us to
miss the stack guard page.

So, introduce stack probes for these struct copies.

It turns out the stack pointer after prolog probing can be sitting
near the very end of the guard page (one `STACK_ALIGN` slot before
the end, which allows a "call" instruction which pushes its
return address to touch the guard page with the return address push).
We don't want to probe with every argument push, though. So change
the prolog probing to insert an "extra" touch at the final SP location
if the previous touch was "too far" away, leaving at least some
buffer zone for un-probed SP adjustments. I chose this to be the
size of the largest SIMD register, which also can get copied to the
argument stack with a "SUB;MOV" sequence.

Added several test case variations showing different large stack
probe situations.

Fix OSX debugging (#23924)

A recent change has incorrectly added dependency on libcoreclrpal.a to
libutilcodenohost.a. This in turn, due to the transitive propagation of
dependencies, caused the libmscordbi to be linked with libcoreclrpal.a.
So libmscordbi contained its own PAL after that change, which is wrong.
libmscordbi should depend on PAL APIs through libmscordaccore that
exports the symbols it needs for it in order to keep just one PAL in the
process.

The fix is to remove the libcoreclrpal.a dependency and export few
new symbols from libmscordaccore instead.
