2016-08-09optionrom: fix compilation with mingw docker targetPaolo Bonzini
Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE, hence --enable-debug disables optimization. This is not acceptable for ROMs, which should override CFLAGS to force inclusion of -O2. Second, PE stores global constructors and destructors using the following linker script snippet: ___CTOR_LIST__ = .; __CTOR_LIST__ = . ; LONG (-1);*(.ctors); *(.ctor); *(SORT(.ctors.*)); LONG (0); ___DTOR_LIST__ = .; __DTOR_LIST__ = . ; LONG (-1); *(.dtors); *(.dtor); *(SORT(.dtors.*)); LONG (0); The LONG directives cause the .img files to be 16 bytes too large; the recently added check to signrom.py catches this. To fix this, replace -T and -e options with a linker script. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-08-09build-sys: fix building with make CFLAGS=.. argumentMarc-André Lureau
When calling make with a CFLAGS=.. argument, the -g/-O filter is not applied, which may result with build failure with ASAN for example. It could be solved with an 'override' directive on CFLAGS, but that would actually prevent setting different CFLAGS manually. Instead, filter the CFLAGS argument from the top-level Makefile (so you could still call make with a different CFLAGS argument on a rom/Makefile manually) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20160805082421.21994-2-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-07-29optionrom: fix detection of -Wa,-32Paolo Bonzini
The cc-option macro runs $(CC) in -S mode (generate assembly) to avoid a pointless run of the assembler. However, this does not work when you want to detect support for cc->as option passthrough. clang ignores -Wa unless -c is provided, and exits successfully even if the -Wa,-32 option is not supported.

2016-07-10build: Use $(AS) for optionrom explicitlyRichard Henderson
For clang before 3.5, -fno-integrated-as does not exist, so the workaround in 5f6f0e27fb24 fails to build. Use clang's default assembler for linux-user/safe-syscall.S, and explicitly change to use the system assembler for the option roms.

2014-02-17Fix QEMU build on OpenBSD on x86 archsBrad
This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled. Check in configure whether the compiler supports the flags for disabling PIE, and if it does then use them for building the ROMs. This fixes the following buildbot failure: >From the OpenBSD buildbots..

2010-01-08Use vpath directivePaolo Bonzini
The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.

2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf
We already have a working multiboot implementation that uses fw_cfg to get its kernel module etc. data in int19 runtime now. So what's missing is a working linux boot option rom. While at it I figured it would be a good idea to take the opcode generator out of pc.c and instead use a proper option rom, like we do with multiboot. So here it is - an fw_cfg using option rom for -kernel with linux! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
