commit 981c08ce72f5b8729381ddebf2f3fe5f1e000638
Author: Tom Tromey <tom@tromey.com>
Date: Wed Apr 1 14:09:52 2020 -0600
Change how complex types are printed in C
GCC accepts the "i" suffix for complex numbers. I think this is nicer
to read than the current output, so this patch changes the C code to
print complex numbers this way.
gdb/ChangeLog
2020-04-01 Tom Tromey <tom@tromey.com>
* c-valprint.c (c_decorations): Change complex suffix to "i".
