29// Guidelines (in no particular order):
30// 1. Avoid relying on pattern ordering to give preference to one pattern
31//    over another, prefer using AddedComplexity instead. The reason for
32//    this is to avoid unintended conseqeuences (caused by altering the
33//    order) when making changes. The current order of patterns in this
34//    file obviously does play some role, but none of the ordering was
35//    deliberately chosen (other than to create a logical structure of
36//    this file). When making changes, adding AddedComplexity to existing
37//    patterns may be needed.
38// 2. Maintain the logical structure of the file, try to put new patterns
39//    in designated sections.
40// 3. Do not use A2_combinew instruction directly, use Combinew fragment
41//    instead. It uses REG_SEQUENCE, which is more amenable to optimizations.
42// 4. Most selection macros are based on PatFrags. For DAGs that involve
43//    SDNodes, use pf1/pf2 to convert them to PatFrags. Use common frags
44//    whenever possible (see the Definitions section). When adding new
45//    macro, try to make is general to enable reuse across sections.
46// 5. Compound instructions (e.g. Rx+Rs*Rt) are generated under the condition
47//    that the nested operation has only one use. Having it separated in case
48//    of multiple uses avoids duplication of (processor) work.
49// 6. The v4 vector instructions (64-bit) are treated as core instructions,
50//    for example, A2_vaddh is in the "arithmetic" section with A2_add.
51// 7. When adding a pattern for an instruction with a constant-extendable
52//    operand, allow all possible kinds of inputs for the immediate value
53//    (see AnyImm/anyimm and their variants in the Definitions section).

3296// for C code of the form r = (c>='0' && c<='9') ? 1 : 0.
3297// The isdigit transformation relies on two 'clever' aspects:
3298// 1) The data type is unsigned which allows us to eliminate a zero test after
3299//    biasing the expression by 48. We are depending on the representation of
3300//    the unsigned types, and semantics.
3301// 2) The front end has converted <= 9 into < 10 on entry to LLVM.
3302//
3303// For the C code:
3304//   retval = (c >= '0' && c <= '9') ? 1 : 0;
3305// The code is transformed upstream of llvm into
3306//   retval = (c-48) < 10 ? 1 : 0;
