Subject: [PATCH] Remove redundant YYLOC global declaration
gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
26 | extern YYLTYPE yylloc;
| ^~~~~~
In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
127 | extern YYLTYPE yylloc;
| ^~~~~~
cc1: all warnings being treated as errors
which means the declaration is completely redundant and can just be
dropped.
