From 194174a371b16dfc24960d1e33371c0a7ef1c2c2 Mon Sep 17 00:00:00 2001 From: Thomas Martitz Date: Fri, 27 Aug 2010 00:29:50 +0000 Subject: 2nd try: Introduce a small api for loading code (codecs,plugins) from disk/memory. It's a used by codec/plugin loading and vastly reduces code duplication. It's also a step forward in getting rid of libuisimulator in the application ports. Apparently sh needs linker symbols prefixed with _ even if they're referenced without from C code. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27902 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugins/plugin_crt0.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'apps/plugins/plugin_crt0.c') diff --git a/apps/plugins/plugin_crt0.c b/apps/plugins/plugin_crt0.c index 536eccaffa..e34124c5a2 100644 --- a/apps/plugins/plugin_crt0.c +++ b/apps/plugins/plugin_crt0.c @@ -32,6 +32,8 @@ PLUGIN_HEADER #define EXIT_MAGIC 0x0CDEBABE extern enum plugin_status plugin_start(const void*); +extern unsigned char plugin_bss_start[]; +extern unsigned char plugin_end_addr[]; static jmp_buf __exit_env; /* only 1 atexit handler for now, chain in the exit handler if you need more */ @@ -61,6 +63,10 @@ enum plugin_status plugin__start(const void *param) int exit_ret; enum plugin_status ret; + /* zero out the bss section */ +#if (CONFIG_PLATFORM & PLATFORM_NATIVE) + rb->memset(plugin_bss_start, 0, plugin_end_addr - plugin_bss_start); +#endif /* we come back here if exit() was called or the plugin returned normally */ exit_ret = setjmp(__exit_env); if (exit_ret == 0) -- cgit v1.2.3
