I noticed my IDE (VSCode) starting to automatically trim trailing
whitespaces on save, despite the setting for it being disabled. I
realized that this is because the .editorconfig file now has
trim_trailing_whitespace = true
for many file types. If we have this EditorConfig setting forcing
editors to trim trailing whitespaces, I think it would make sense to
clean up trailing whitespaces from our files. Otherwise, people will
always get spurious whitespace changes when editing these files.
I did a mass cleanup using this command:
$ find gdb gdbserver gdbsupport -type f \( \
-name "*.c" -o \
-name "*.h" -o \
-name "*.cc" -o \
-name "*.texi" -o \
-name "*.exp" -o \
-name "*.tcl" -o \
-name "*.py" -o \
-name "*.s" -o \
-name "*.S" -o \
-name "*.asm" -o \
-name "*.awk" -o \
-name "*.ac" -o \
-name "Makefile*" -o \
-name "*.sh" -o \
-name "*.adb" -o \
-name "*.ads" -o \
-name "*.d" -o \
-name "*.go" -o \
-name "*.F90" -o \
-name "*.f90" \
\) -exec sed -ri 's/[ \t]+$//' {} +
I then did an autotools regen, because we don't actually want to change
the Makefile and Makefile.in files that are generated.
