◆ tryParseAlign()
Looks into the <parameters> part of the mangled name in search of a valid 'aligned' clause.
The function should be invoked after parsing a parameter via tryParseParameter.
On success, it removes the parsed parameter from ParseString, sets PKind to the correspondent enum value, sets StepOrPos accordingly, and return success. On a syntax error, it return a parsing error. If nothing is parsed, it returns std::nullopt.

◆ tryParseCompileTimeLinearToken()
|
static |
The function looks for the following strings at the beginning of the input string ParseString:
<token> {"n"} <number>
On success, it removes the parsed parameter from ParseString, sets PKind to the correspondent enum value, sets LinearStep to <number>, and return success. On a syntax error, it return a parsing error. If nothing is parsed, it returns std::nullopt.
The function expects <token> to be one of "l", "R", "U" or "L".

◆ tryParseISA()
Extracts the <isa> information from the mangled string, and sets the ISA accordingly.
If successful, the <isa> token is removed from the input string MangledName.

◆ tryParseVLEN()
|
static |
Extract the <vlen> information from the mangled string, and sets ParsedVF accordingly.
A <vlen> == "x" token is interpreted as a scalable vector length and the boolean is set to true, otherwise a nonzero unsigned integer will be directly used as a VF. On success, the <vlen> token is removed from the input string ParseString.
