-Subject: [PATCH 1/1] c++: tsubst_function_decl and excess arg levels
- [PR100102]
-
-Here, when instantiating the dependent alias template
-duration::__is_harmonic with args={{T,U},{int}}, we find ourselves
-substituting the function decl _S_gcd.  Since we have more arg levels
-than _S_gcd has parm levels, an old special case in tsubst_function_decl
-causes us to unwantedly reduce args to its innermost level, yielding
-args={int}, which leads to a nonsensical substitution into the decl
-context and eventually a crash.
-
-The comment for this special case refers to three examples for which we
-ought to see more arg levels than parm levels here, but none of the
-examples actually demonstrate this.  In the first example, when
-defining S<int>::f(U) parms_depth is 2 and args_depth is 1, and
-later when instantiating say S<int>::f<char> both depths are 2.  In the
-second example, when substituting the template friend declaration
-parms_depth is 2 and args_depth is 1, and later when instantiating f
-both depths are 1.  Finally, the third example is invalid since we can't
-specialize a member template of an unspecialized class template like
-that.
-
-Given that this reduction code seems no longer relevant for its
-documented purpose and that it causes problems as in the PR, this patch
-just removes it.  Note that as far as bootstrap/regtest is concerned,
-this code is dead; the below two tests would be the first to reach it.
