reland [IR] make -stack-alignment= into a module attr

2021-06-08T17:59:46+00:00

Relands commit 433c8d950cb3a1fa0977355ce0367e8c763a3f13 with fixes for
MIPS.

Similar to D102742, specifying the stack alignment via CodegenOpts means
that this flag gets dropped during LTO, unless the command line is
re-specified as a plugin opt. Instead, encode this information as a
module level attribute so that we don't have to expose this llvm
internal flag when linking the Linux kernel with LTO.

Looks like external dependencies might need a fix:

[MIPS] Implement support for -mstack-alignment.

2017-08-14T21:49:38+00:00

Summary:
This is modeled on the implementation for x86 which stores the command line
option in a 'StackAlignOverride' field in MipsSubtarget and then uses this
to compute a 'stackAlignment' value in
MipsSubtarget::initializeSubtargetDependencies.

The stackAlignment() method in MipsSubTarget is renamed to getStackAlignment()
and returns the computed 'stackAlignment'.

[MIPS] Use ABI to determine stack alignment.

2017-08-11T22:07:56+00:00

Summary:
The stack alignment depends on the ABI (16 bytes for N32 and N64 and 8
bytes for O32), not the CPU type.
