From: Rob Savoye Date: Wed, 4 Dec 1996 00:56:56 +0000 (+0000) Subject: * configure.in: Look for libtermcap.a. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a665caa644857954b195eed35957f0d4af86106f;p=binutils-gdb.git * configure.in: Look for libtermcap.a. * Makefile.in: Only link in -ltermcap if it exists. * erc32.c: Update to version 2.6a. Fix uart handling. * exec.c: Update to version 2.6a. Add sparclite support. * float.c: Update to version 2.6a. Convert comments to preprocessor warnings. Add __setfpucw() for i385 hosts so floating point exceptions work. * func.c: Update to version 2.6a. Fix uart handling, add support for user error traps. * help.c: Update to version 2.6a. Add help note on user error traps. * interf.c: Update to version 2.6a. Fix uart handling, and add sparclite support. * examples/gccx: Use sparclite cross compiler, not native gcc. * examples/srt0.S: Use "mov" rather than "wr" for manipulating the psr register. --- diff --git a/sim/erc32/ChangeLog b/sim/erc32/ChangeLog index 1ec47c1d367..bf18bc9d43c 100644 --- a/sim/erc32/ChangeLog +++ b/sim/erc32/ChangeLog @@ -1,3 +1,28 @@ +Tue Dec 3 11:54:37 1996 Rob Savoye + + * configure.in: Look for libtermcap.a. + * Makefile.in: Only link in -ltermcap if it exists. + * erc32.c: Update to version 2.6a.
