From a4dcff16c8cb2762bfdbe034ed6b8b52bbd11a5d Mon Sep 17 00:00:00 2001 From: Marcel Moolenaar Date: Thu, 24 May 2012 20:12:46 +0000 Subject: Allow building for the PowerPC EABI by providing a dummy __eabi() function. The purpose of the __eabi() function is to set up the runtime and is called first thing by main(). The runtime is already set up for us prior to caling main, so there's nothing to do for us in the EABI case. --- lib/libc/powerpc/Symbol.map | 1 + lib/libc/powerpc/gen/Makefile.inc | 2 +- lib/libc/powerpc/gen/eabi.S | 33 +++++++++++++++++++++++++++++++++ 3 files changed, 35 insertions(+), 1 deletion(-) create mode 100644 lib/libc/powerpc/gen/eabi.S (limited to 'lib/libc/powerpc') diff --git a/lib/libc/powerpc/Symbol.map b/lib/libc/powerpc/Symbol.map index 14b48114a497b..83ed871843d5e 100644 --- a/lib/libc/powerpc/Symbol.map +++ b/lib/libc/powerpc/Symbol.map @@ -11,6 +11,7 @@ FBSD_1.0 { /* PSEUDO syscalls */ _exit; + __eabi; _mcount; _setjmp; _longjmp; diff --git a/lib/libc/powerpc/gen/Makefile.inc b/lib/libc/powerpc/gen/Makefile.inc index 79a274656e820..81c6a698fac8b 100644 --- a/lib/libc/powerpc/gen/Makefile.inc +++ b/lib/libc/powerpc/gen/Makefile.inc @@ -1,6 +1,6 @@ # $FreeBSD$ -SRCS += _ctx_start.S fabs.S flt_rounds.c fpgetmask.c fpgetround.c \ +SRCS += _ctx_start.S eabi.S fabs.S flt_rounds.c fpgetmask.c fpgetround.c \ fpgetsticky.c fpsetmask.c fpsetround.c getcontextx.c \ infinity.c ldexp.c makecontext.c _setjmp.S \ setjmp.S sigsetjmp.S signalcontext.c syncicache.c \ diff --git a/lib/libc/powerpc/gen/eabi.S b/lib/libc/powerpc/gen/eabi.S new file mode 100644 index 0000000000000..59c231123f205 --- /dev/null +++ b/lib/libc/powerpc/gen/eabi.S @@ -0,0 +1,33 @@ +/* + * Copyright (c) 2011 Marcel Moolenaar + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
