From 371b76ef3e221248c7df49906014037c66292901 Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Mon, 11 Jun 2001 19:25:59 +0000 Subject: 2001-06-11 Egor Duda * libc/ctype/ctype_.c: When compiled with gcc on platforms with signed char, make _ctype_[-128] ... _ctype[-1] refer to initialized memory region. Platform can define COMPACT_CTYPE to avoid allocation of the additional 128 bytes of data. Add pointer to _ctype_ array. Always initialize all _ctype_ array elements. --- newlib/ChangeLog | 9 ++++++ newlib/libc/ctype/ctype_.c | 78 ++++++++++++++++++++++++++++++++++++---------- 2 files changed, 71 insertions(+), 16 deletions(-) (limited to 'newlib') diff --git a/newlib/ChangeLog b/newlib/ChangeLog index 81b62e48a..c568283c0 100644 --- a/newlib/ChangeLog +++ b/newlib/ChangeLog @@ -1,3 +1,12 @@ +2001-06-11 Egor Duda + + * libc/ctype/ctype_.c: When compiled with gcc on platforms + with signed char, make _ctype_[-128] ... _ctype[-1] refer to + initialized memory region.
