File 0091-dump-Make-DumpState-and-endian-conv.patch of Package qemu-linux-user.3557
From 6b9fa7cebf3a4c4ee375356c46a9f4c0df4edfce Mon Sep 17 00:00:00 2001 From: Bharata B Rao <bharata@linux.vnet.ibm.com> Date: Mon, 19 May 2014 19:57:44 +0200 Subject: [PATCH] dump: Make DumpState and endian conversion routines available for arch-specific dump code Make DumpState and endian conversion routines available for arch-specific dump code by moving into dump.h. DumpState will be needed by arch-specific dump code to access target endian information from DumpState->ArchDumpInfo. Also break the dependency of dump.h from stubs/dump.c by creating a separate dump-arch.h. This patch doesn't change any functionality. Signed-off-by: Bharata B Rao <bharata@linux.ibm.com> [ rebased on top of current master branch, renamed endian helpers to cpu_to_dump{16,32,64}, pass a DumpState * argument to endian helpers, Greg Kurz <gkurz@linux.vnet.ibm.com> ] Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> [agraf: fix to apply] Signed-off-by: Alexander Graf <agraf@suse.de> --- dump.c | 231 ++++++++++++++++++--------------------------- include/sysemu/dump-arch.h | 28 ++++++ include/sysemu/dump.h | 45 +++++++-- stubs/dump.c | 2 +- 4 files changed, 154 insertions(+), 152 deletions(-) create mode 100644 include/sysemu/dump-arch.h diff --git a/dump.c b/dump.c index 97d2c8d..ce646bc 100644 --- a/dump.c +++ b/dump.c @@ -36,9 +36,9 @@ #define ELF_MACHINE_UNAME "Unknown" #endif -static uint16_t cpu_convert_to_target16(uint16_t val, int endian) +uint16_t cpu_to_dump16(DumpState *s, uint16_t val) { - if (endian == ELFDATA2LSB) { + if (s->dump_info.d_endian == ELFDATA2LSB) { val = cpu_to_le16(val);
