Subject: [PATCH][vectorizer] Remove blank debug lines after dump_gimple_stmt
Date: Mon, 06 Jun 2016 12:46:00 -0000 [thread overview]
Message-ID: <D37B2F3F.FA9A%alan.hayward@arm.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1354 bytes --]
Lots of code calls dump_gimple_stmt then print a newline, however
dump_gimple_stmt will print a newline itself. This makes the vectorizer
debug
file messy. I think the confusion is because dump_generic_expr does NOT
print a
newline. This patch removes all prints of a newline direcly after a
dump_gimple_stmt.
Tested by examining a selection of vect dump files.
gcc/
