This patch adds support for arm_sve.h. I've tried to split all the
groundwork out into separate patches, so this is mostly adding new code
rather than changing existing code.
The C++ frontend seems to handle correct ACLE code without modification,
even in length-agnostic mode. The C frontend is close; the only correct
construct I know it doesn't handle is initialisation. E.g.:
svbool_t pg = svptrue_b8 ();
produces:
variable-sized object may not be initialized
although:
svbool_t pg; pg = svptrue_b8 ();
works fine. This can be fixed by changing:
{
/* A complete type is ok if size is fixed. */
- if (TREE_CODE (TYPE_SIZE (TREE_TYPE (decl))) != INTEGER_CST
+ if (!poly_int_tree_p (TYPE_SIZE (TREE_TYPE (decl)))
|| C_DECL_VARIABLE_SIZE (decl))
{
error ("variable-sized object may not be initialized");
in c/c-decl.c:start_decl.
Invalid code is likely to trigger ICEs, so this isn't ready for general
use yet. However, it seemed better to apply the patch now and deal with
diagnosing invalid code as a follow-up. For one thing, it means that
we'll be able to provide testcases for middle-end changes related
to SVE vectors, which has been a problem until now. (I already have
a series of such patches lined up.)
The patch includes some tests, but the main ones need to wait until the
PCS support has been applied.
Thanks a lot to Kugan and Prathamesh for their help with this.
Tested on aarch64-linux-gnu (with and without SVE) and aarch64_be-elf.
Applied as r277563.
