tcg: Remove support for ia64 as host

2017-09-05T19:39:25+00:00

We threatened to remove ia64 as host in v2.9.0. Its time has now come. There are still some usages of defined(__ia64__) throughout the source code that would be triggered if one were to enable TCI on an ia64 host. Leave those alone for now. Signed-off-by: Richard Henderson

tcg: Introduce goto_ptr opcode and tcg_gen_lookup_and_goto_ptr

2017-06-05T16:25:42+00:00

Instead of exporting goto_ptr directly to TCG frontends, export tcg_gen_lookup_and_goto_ptr(), which calls goto_ptr with the pointer returned by the lookup_tb_ptr() helper. This is the only use case we have for goto_ptr and lookup_tb_ptr, so having this function is very convenient. Furthermore, it trivially allows us to avoid calling the lookup helper if goto_ptr is not implemented by the backend. Reviewed-by: Alex Bennée Signed-off-by: Emilio G.

tcg: Add opcode for ctpop

2017-01-10T16:48:56+00:00

The number of actual invocations of ctpop itself does not warrent an opcode, but it is very helpful for POWER7 to use in generating an expansion for ctz. Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

tcg: Pass the opcode width to target_parse_constraint

2017-01-10T16:06:11+00:00

This will let us choose how to interpret a given constraint depending on whether the opcode is 32- or 64-bit. Which will let us share more constraint combinations between opcodes. At the same time, change the interface to return the advanced pointer instead of passing it in/out by reference. Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

tcg: Transition flat op_defs array to a target callback

2017-01-10T16:06:11+00:00

This will allow the target to tailor the constraints to the auto-detected ISA extensions. Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

tcg: Add field extraction primitives

2017-01-10T15:59:11+00:00

Adds tcg_gen_extract_* and tcg_gen_sextract_* for extraction of fixed position bitfields, much like we already have for deposit. Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

tcg: Support arbitrary size + alignment

2016-09-16T15:12:06+00:00

Previously we allowed fully unaligned operations, but not operations that are aligned but with less alignment than the operation size. In addition, arm32, ia64, mips, and sparc had been omitted from the previous overalignment patch, which would have led to that alignment being enforced. Signed-off-by: Richard Henderson

tcg: Clean up tcg-target.h header guards

2016-07-12T14:19:16+00:00

These use guard symbols like TCG_TARGET_$target. scripts/clean-header-guards.pl doesn't like them because they don't match their file name (they should, to make guard collisions less likely). Clean them up: use guard symbol $target_TCG_TARGET_H for tcg/$target/tcg-target.h. Signed-off-by: Markus Armbruster Reviewed-by: Richard Henderson
