From: John Hodge Date: Wed, 12 Oct 2011 03:12:29 +0000 (+0800) Subject: Major build system changes X-Git-Tag: rel0.12~3 X-Git-Url: https://git.ucc.asn.au/?a=commitdiff_plain;h=dc8801cc0b5ed911a775cfc2ea853048f7a00db1;p=tpg%2Facess2.git Major build system changes - Implemented ARMv7 userspace - Shifted build system about to do so > `make all` processes user apps first This is so they are compiled for the initrd > Syscalls header changed to use #define instead of enum Allows ARMv7 assembly file to use it - Moved most of my libgcc functions to ld-acess > ld-acess needed them, so remove code duplication NOTE: Broke dependencies for nasm in user code - I need to properly separate NASM and GAS objects, will do that in next commit. --- diff --git a/Kernel/GenSyscalls.php b/Kernel/GenSyscalls.php index 1876046b..d451d1dd 100644 --- a/Kernel/GenSyscalls.php +++ b/Kernel/GenSyscalls.php @@ -27,7 +27,6 @@ $lHeader = "/* #ifndef _SYSCALLS_H #define _SYSCALLS_H -enum eSyscalls { "; $i = 0; foreach($lSyscalls as $num=>$call) @@ -37,9 +36,8 @@ foreach($lSyscalls as $num=>$call) $lAsmInc .= "\n"; } -
