From cebb191903d3562d848b70dd51060b05e92435b9 Mon Sep 17 00:00:00 2001 From: Thomas Koenig Date: Sun, 8 Oct 2017 12:54:40 +0000 Subject: [PATCH] dump_prase_tree (show_symbol): Output list of variables in NAMELIST. 2017-10-08 Thomas Koenig * dump_prase_tree (show_symbol): Output list of variables in NAMELIST. (show_code_node): Add new line for ELSE and END DO for DO CONCURRENT. * invoke.texi: Document that the output of -fdump-fortran-original, -fdump-fortran-optimized and -fdump-parse-tree is unsable and may lead to ICEs.
