Subject: [PATCH] symbol: preserve address space qualifiers with typeof()
Date: Sat, 18 Oct 2025 12:35:13 +0300 [thread overview]
Message-ID: <aPNfUShPJ3zaAeYp@stanley.mountain> (raw)
When we're parsing typeof(var) we then preserve the address space
qualifiers as well. Otherwise it leads to warnings like this:
"warning: cast removes address space '__seg_gs' of expression"
