2020-06-24x86: Add Cooper Lake detection with AVX512BF16H.J. Lu1-1/+9
All Sky Lake family processors have the same CPUID model number, 0x55. The differences are Cascade Lake has AVX512VNNI and Cooper Lake has AVX512VNNI + AVX512BF16. Check AVX512BF16 for Cooper Lake.

2020-06-24x86: Share _isa_names_table and use cpuinfo.hH.J. Lu4-908/+306
Both driver-i386.c and libgcc use CPUID to detect the processor name as well as available ISAs. To detect the same processor or ISAs, the same detection logic is duplicated in 2 places. Sometimes only one place was up to date or got it right. Sometimes both places got it wrong. 1. Add common/config/i386/i386-isas.h to define _isa_names_table. 2.

Use common/config/i386/cpuinfo.h to check available ISAs and detect newer Intel processors in driver-i386.c and builtin_target.c. 5.

The __detail::__to_chars_2 function assumes it won't be called with zero values. However, when the output buffer is empty the caller doesn't handle zero values correctly, and calls __to_chars_2 with a zero value, resulting in an overflow of the empty buffer.

In i386-builtins.c, arch_names_table is used to to map architecture name string to internal model. A switch statement is used to map internal processor name to architecture name string and internal priority. model and priority are added to processor_alias_table so that a single entry contains architecture name string, internal processor name, internal model and internal priority. 6 entries are appended for i386-builtins.c, which have special architecture name strings: amd, amdfam10h, amdfam15h, amdfam17h, shanghai and istanbul, and pta_size is adjusted to exclude them.

2020-06-24emit SLP vectorized loads earlierRichard Biener4-109/+213
This makes sure to emit SLP vectorized loads where the first scalar load is. This makes SLP dependence checking more powerful because hoisting loads can use TBAA and it increases the freedom for vector placement when there are constraints from live lanes. Vectorized shifts block inserting vectorized stmts always after vectorized defs because it ends up using the original scalar operand even when the SLP graph indicates the shift operand is vectorized (and we actually emit and cost those stmts). vect_slp_analyze_and_verify_node_alignment shows we need alignment for too many places, this is a temporary solution and my plan is to have a single meta-info for a dataref group instead (also getting rid of DR_GROUP_FIRST/NEXT_ELEMENT). 2020-06-24 Richard Biener <rguenther@suse.de> * tree-vectorizer.h (vect_find_first_scalar_stmt_in_slp): Declare. * tree-vect-data-refs.c (vect_preserves_scalar_order_p): Simplify for new position of vectorized SLP loads.

2020-06-23arm: PR target/95646: Do not clobber callee saved registers with CMSEAndre Simoes Dias Vieira2-1/+33
As reported in bugzilla when the -mcmse option is used while compiling for size (-Os) with a thumb-1 target the generated code will clear the registers r7-r10. These however are callee saved and should be preserved accross ABI boundaries. The reason this happens is because these registers are made "fixed" when optimising for size with Thumb-1 in a way to make sure they are not used, as pushing and popping hi-registers requires extra moves to and from LO_REGS. To fix this, this patch uses 'callee_saved_reg_p', which accounts for this optimisation, instead of 'call_used_or_fixed_reg_p'. Be aware of 'callee_saved_reg_p''s definition, as it does still take call used registers into account, which aren't callee_saved in my opinion, so it is a rather misnoemer, works in our advantage here though as it does exactly what we need.

2020-06-22build: Use -include instead of conditional include.David Edelsohn8-24/+8
Automake and GNU Make both use the endif keyword, which conflicts and elicits an error for matching if/ifdef and endif.
