-/// \brief Simple representation of an unsigned floating point.
-///
-/// UnsignedFloat is a unsigned floating point number. It uses simple
-/// saturation arithmetic, and every operation is well-defined for every value.
-///
-/// The number is split into a signed exponent and unsigned digits. The number
-/// represented is \c getDigits()*2^getExponent(). In this way, the digits are
-/// much like the mantissa in the x87 long double, but there is no canonical
-/// form, so the same number can be represented by many bit representations
-/// (it's always in "denormal" mode).
-///
-/// UnsignedFloat is templated on the underlying integer type for digits, which
-/// is expected to be one of uint64_t, uint32_t, uint16_t or uint8_t.
-///
-/// Unlike builtin floating point types, UnsignedFloat is portable.
-///
-/// Unlike APFloat, UnsignedFloat does not model architecture floating point
-/// behaviour (this should make it a little faster), and implements most
-/// operators (this makes it usable).
-///
-/// UnsignedFloat is totally ordered. However, there is no canonical form, so
-/// there are multiple representations of most scalars. E.g.:
-///
-/// UnsignedFloat(8u, 0) == UnsignedFloat(4u, 1)
-/// UnsignedFloat(4u, 1) == UnsignedFloat(2u, 2)
-/// UnsignedFloat(2u, 2) == UnsignedFloat(1u, 3)
-///
-/// UnsignedFloat implements most arithmetic operations. Precision is kept
-/// where possible. Uses simple saturation arithmetic, so that operations
-/// saturate to 0.0 or getLargest() rather than under or overflowing. It has
-/// some extra arithmetic for unit inversion. 0.0/0.0 is defined to be 0.0.
-/// Any other division by 0.0 is defined to be getLargest().
-///
-/// As a convenience for modifying the exponent, left and right shifting are
-/// both implemented, and both interpret negative shifts as positive shifts in
-/// the opposite direction.
-///
-/// Exponents are limited to the range accepted by x87 long double. This makes
-/// it trivial to add functionality to convert to APFloat (this is already
-/// relied on for the implementation of printing).
-///
-/// The current plan is to gut this and make the necessary parts of it (even
-/// more) private to BlockFrequencyInfo.

+/// Function Length : 11-bit field providing the length of the entire function

+/// 4KB, a full .xdata record must be used instead
+/// Ret : 2-bit field indicating how the function returns
+/// - 00 = return via pop {pc} (the L bit must be set)
+/// - 01 = return via 16-bit branch
+/// - 10 = return via 32-bit branch
+/// - 11 = no epilogue; useful for function fragments that may only contain a
+/// prologue but the epilogue is elsewhere
+/// H : 1-bit flag indicating whether the function "homes" the integer parameter
+/// registers (r0-r3), allocating 16-bytes on the stack
+/// Reg : 3-bit field indicating the index of the last saved non-volatile
+/// register. If the R bit is set to 0, then only integer registers are
+/// saved (r4-rN, where N is 4 + Reg). If the R bit is set to 1, then
+/// only floating-point registers are being saved (d8-dN, where N is
+/// 8 + Reg). The special case of the R bit being set to 1 and Reg equal
+/// to 7 indicates that no registers are saved.
+/// R : 1-bit flag indicating whether the non-volatile registers are integer or
+/// floating-point. 0 indicates integer, 1 indicates floating-point. The
+/// special case of the R-flag being set and Reg being set to 7 indicates
+/// that no non-volatile registers are saved.
+/// L : 1-bit flag indicating whether the function saves/restores the link
+/// register (LR)
+/// C : 1-bit flag indicating whether the function includes extra instructions
+/// to setup a frame chain for fast walking. If this flag is set, r11 is
+/// implicitly added to the list of saved non-volatile integer registers.
+/// Stack Adjust : 10-bit field indicating the number of bytes of stack that are
+/// allocated for this function. Only values between 0x000 and
+/// 0x3f3 can be directly encoded. If the value is 0x3f4 or
+/// greater, then the low 4 bits have special meaning as follows:
+/// - Bit 0-1
+/// indicate the number of words' of adjustment (1-4), minus 1
+/// - Bit 2
+/// indicates if the prologue combined adjustment into push
+/// - Bit 3
+/// indicates if the epilogue combined adjustment into pop
+///
+/// RESTRICTIONS:
+/// - IF C is SET:
+/// + L flag must be set since frame chaining requires r11 and lr
+/// + r11 must NOT be included in the set of registers described by Reg
+/// - IF Ret is 0:
+/// + L flag must be set
+
+// NOTE: RuntimeFunction is meant to be a simple class that provides raw access

+/// \brief Simple representation of a scaled number.
+///
+/// ScaledNumber is a number represented by digits and a scale. It uses simple
+/// saturation arithmetic and every operation is well-defined for every value.
+/// It's somewhat similar in behaviour to a soft-float, but is *not* a
+/// replacement for one. If you're doing numerics, look at \a APFloat instead.
+/// Nevertheless, we've found these semantics useful for modelling certain cost
+/// metrics.
+///
+/// The number is split into a signed scale and unsigned digits. The number
+/// represented is \c getDigits()*2^getScale(). In this way, the digits are
+/// much like the mantissa in the x87 long double, but there is no canonical
+/// form so the same number can be represented by many bit representations.
+///
+/// ScaledNumber is templated on the underlying integer type for digits, which
+/// is expected to be unsigned.
+///
+/// Unlike APFloat, ScaledNumber does not model architecture floating point
+/// behaviour -- while this might make it a little faster and easier to reason
+/// about, it certainly makes it more dangerous for general numerics.
+///
+/// ScaledNumber is totally ordered. However, there is no canonical form, so
+/// there are multiple representations of most scalars. E.g.:
+///
+/// ScaledNumber(8u, 0) == ScaledNumber(4u, 1)
+/// ScaledNumber(4u, 1) == ScaledNumber(2u, 2)
+/// ScaledNumber(2u, 2) == ScaledNumber(1u, 3)
+///
+/// ScaledNumber implements most arithmetic operations. Precision is kept
+/// where possible. Uses simple saturation arithmetic, so that operations
+/// saturate to 0.0 or getLargest() rather than under or overflowing. It has
+/// some extra arithmetic for unit inversion. 0.0/0.0 is defined to be 0.0.
+/// Any other division by 0.0 is defined to be getLargest().
+///
+/// As a convenience for modifying the exponent, left and right shifting are
+/// both implemented, and both interpret negative shifts as positive shifts in
+/// the opposite direction.
+///
+/// Scales are limited to the range accepted by x87 long double. This makes
+/// it trivial to add functionality to convert to APFloat (this is already
+/// relied on for the implementation of printing).
+///
+/// Possible (and conflicting) future directions:
+///
+/// 1. Turn this into a wrapper around \a APFloat.
+/// 2. Share the algorithm implementations with \a APFloat.
+/// 3. Allow \a ScaledNumber to represent a signed number.

+//
+// This file implements the SetTheory class that computes ordered sets of
+// Records from DAG expressions. Operators for standard set operations are
+// predefined, and it is possible to add special purpose set operators as well.
+//
+// The user may define named sets as Records of predefined classes. Set
+// expanders can be added to a SetTheory instance to teach it how to find the
+// elements of such a named set.
+//
+// These are the predefined operators. The argument lists can be individual
+// elements (defs), other sets (defs of expandable classes), lists, or DAG
+// expressions that are evaluated recursively.
+//
+// - (add S1, S2 ...) Union sets. This is also how sets are created from element
+// lists.
+//
+// - (sub S1, S2, ...) Set difference. Every element in S1 except for the
+// elements in S2, ...
+//
+// - (and S1, S2) Set intersection. Every element in S1 that is also in S2.
+//
+// - (shl S, N) Shift left. Remove the first N elements from S.
+//
+// - (trunc S, N) Truncate. The first N elements of S.
+//
+// - (rotl S, N) Rotate left. Same as (add (shl S, N), (trunc S, N)).
+//
+// - (rotr S, N) Rotate right.
+//
+// - (decimate S, N) Decimate S by picking every N'th element, starting with
+// the first one. For instance, (decimate S, 2) returns the even elements of
+// S.
+//
+// - (sequence "Format", From, To) Generate a sequence of defs with printf.
+// For instance, (sequence "R%u", 0, 3) -> [ R0, R1, R2, R3 ]

-// This is a utility class for instrumentation passes (like AddressSanitizer

-//
-// The list can also specify categories for specific globals, which can be used
-// to instruct an instrumentation pass to treat certain functions or global
-// variables in a specific way, such as by omitting certain aspects of
-// instrumentation while keeping others, or informing the instrumentation pass
-// that a specific uninstrumentable function has certain semantics, thus
-// allowing the pass to instrument callers according to those semantics.
-//
-// For example, AddressSanitizer uses the "init" category for globals whose
-// initializers should not be instrumented, but which in all other respects
-// should be instrumented.
-//
-// Each line contains a prefix, followed by a colon and a wild card expression,
