// These constants capture the various ways in which the inliner's
// scoring phase can adjust a callsite score based on heuristics. They
// fall broadly into three categories:
//
// 1) adjustments based solely on the callsite context (ex: call
// appears on panic path)
//
// 2) adjustments that take into account specific interesting values

<p>
The following terms are used to denote specific Unicode character categories:
</p>
<pre class="ebnf">
newline        = /* the Unicode code point U+000A */ .
unicode_char   = /* an arbitrary Unicode code point except newline */ .
unicode_letter = /* a Unicode code point categorized as "Letter" */ .
unicode_digit  = /* a Unicode code point categorized as "Number, decimal digit" */ .
</pre>

		//  storeUse contains stores which are used by a subsequent store.
		loadUse.clear()

<p>
In <a href="https://www.unicode.org/versions/Unicode8.0.0/">The Unicode Standard 8.0</a>,
Section 4.5 "General Category" defines a set of character categories.
Go treats all characters in any of the Letter categories Lu, Ll, Lt, Lm, or Lo
as Unicode letters, and those in the Number category Nd as Unicode digits.
