PURPOSE
This is a readme file to note the changes made to the binutils-2.33.1 source
code in to build its GNU demangler. The files in this directory are used to create a demangling
utility during the full build process.
COPIED SOURCE CODE / BUILDING RESTRICTIONS
Most of the files used to build the Ghidra GNU demangler are copied from binutils and have
not been changed. Further, the files in this directory are a small subset of the files used to
build the binutils suite. By copying specific files we are able to use Make and Visual Studio
to build a stand alone demangler without having to perform the more complicated build needed
to build binutils. Specifically, we do not have to run the configure utility that is
provided by binutils. This is critical, as we are using Visual Studio to build on Windows,
which does not have the configure utility support. If we ever wished to build the entire
binutils suite on Windows, then we would most likely need to use a GNU environment made for
Windows, such as MinGW.
CHANGES TO BINUTILS SOURCE
cp-demangle.c
This file contains a small, one-line change to flush to the standard output stream. Without
this change, the program, when called repeatedly from Java would hang as it attempts to read
characters that are buffered on the native side.
UPDATING
If we ever wish to update to a newer version of binutils, then we will need to re-copy the files
in this directory. That is, unless at least one of the following changes happens:
1) building a stand alone c++filt is simple enough that we can do it on each platform, or
2) we decide to build the entire binutils suite and use the full c++filt binary.

/* Mangled Rust symbols look like this:
_$LT$std..sys..fd..FileDesc$u20$as$u20$core..ops..Drop$GT$::drop::hc68340e1baa4987a
The original symbol is:
<std::sys::fd::FileDesc as core::ops::Drop>::drop
The last component of the path is a 64-bit hash in lowercase hex,
prefixed with "h". Rust does not have a global namespace between
crates, an illusion which Rust maintains by using the hash to
distinguish things that would otherwise have the same symbol.
Any path component not starting with a XID_Start character is
prefixed with "_".
The following escape sequences are used:
"," => $C$
"@" => $SP$
"*" => $BP$
"&" => $RF$
"<" => $LT$
">" => $GT$
"(" => $LP$
")" => $RP$
" " => $u20$

";" => $u3b$
"[" => $u5b$
"]" => $u5d$
"{" => $u7b$
"}" => $u7d$
"~" => $u7e$

This function looks for the following indicators:
1. The hash must consist of "h" followed by 16 lowercase hex digits.
2. As a sanity check, the hash must use between 5 and 15 of the 16
possible hex digits. This is true of 99.9998% of hashes so once
in your life you may see a false negative. The point is to
notice path components that could be Rust hashes but are
probably not, like "haaaaaaaaaaaaaaaa". In this case a false
positive (non-Rust symbol has an important path component
removed because it looks like a Rust hash) is worse than a false
negative (the rare Rust symbol is not demangled) so this sets
the balance in favor of false negatives.
