11 years agolit: Support cancellation on Windows

lit: Support cancellation on Windows

The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.

We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.

COFFDumper: Dump data directory entries.

we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.

PPC: Support dynamic allocas with large alignment

Support for dynamic stack alignments in the PPC backend has been unfinished, in
part because it depends on dynamic stack realignment (which I only just
recently implemented fully). Now we can also support dynamic allocas with
higher than the default target stack alignment (16 bytes).

In order to round-up the requested size to the maximum requested alignment, we
need an additional register to hold the rounded-up size. We're already using one
scavenged register to hold the previous stack-pointer value (which needs to be
stored with the signal-safe stdux update), and so when we have dynamic allocas
and a large alignment, we allocate two emergency spill slots for the scavenger.

11 years agoPPC: Add base-pointer support to builtin setjmp/longjmp
Hal Finkel [Wed, 17 Jul 2013 23:50:51 +0000 (23:50 +0000)]
PPC: Add base-pointer support to builtin setjmp/longjmp

First, this changes the base-pointer implementation to remove an unnecessary
complication (and one that is incompatible with how builtin SjLj is
implemented): instead of using r31 as the base pointer when it is not needed as
a frame pointer, now the base pointer will always be r30 when needed.

Second, we introduce another pseudo register, BP, which is used just like the FP
pseudo register to refer to the base register before we know for certain what
register it will be.

Third, we now save BP into the jmp_buf, and restore r30 from that slot in
longjmp.  If the function that called setjmp did not use a base pointer, then
r30 will be overwritten by the setjmp-calling-function's restore code. FP
restoration (which is restored into r31) works the same way.
