# of the list as an argument to the function. However, Make is
# limited, and using this method you can not easily send spaces.

# "variable append packs":
#
# 1) variable appends can include spaces, and those must be preserved
# 2) variable appends can include assignment strings ":=", and those

// The code here recognizes three major cases:
// A. Fastest: receiver found in the table
// B. Fast: no receiver in the table, and the table is full
// C. Slow: no receiver in the table, free slots in the table
//
// The case A performance is most important, as perfectly-behaved code would end up
// there, especially with larger TypeProfileWidth. The case B performance is
// important as well, this is where bulk of code would land for normally megamorphic
// cases. The case C performance is not essential, its job is to deal with installation
// races, we optimize for code density instead. Case C needs to make sure that receiver
// rows are only claimed once. This makes sure we never overwrite a row for another
// receiver and never duplicate the receivers in the list, making profile type-accurate.
//
// It is very tempting to handle these cases in a single loop, and claim the first slot
// without checking the rest of the table. But, profiling code should tolerate free slots
// in the table, as class unloading can clear them. After such cleanup, the receiver
// we need might be _after_ the free slot. Therefore, we need to let at least full scan
// to complete, before trying to install new slots. Splitting the code in several tight
// loops also helpfully optimizes for cases A and B.
