teythoon/gnumach.git/i386/ldscript, branch masterPersonal GNU Mach development repositoryhttps://darnassus.sceen.net/cgit/teythoon/gnumach.git/atom?h=master2012-03-24T02:17:33ZFix Xen boot after c74adfe2012-03-24T02:17:33ZSamuel Thibaultsamuel.thibault@ens-lyon.org2012-03-24T02:16:39Zurn:sha1:71f231da83fdd75deab3ce1b8643da50b6f574f5
* i386/Makefrag.am (_START_MAP): Define symbol to 0x100000.
* i386/xen/Makefrag.am (_START_MAP): Define symbol to 0xC0000000.
* i386/ldscript: Use _START_MAP instead of hardcoding 0x100000.
Relocate kernel at bootup2012-03-24T02:05:31ZSamuel Thibaultsamuel.thibault@ens-lyon.org2012-03-24T02:01:01Zurn:sha1:c74adfecd0b21ea84f7e98629549f7489c78edc9
Grub is not able to map us at high addresses. We can however make it load us at
low addresses (through the linker script mapping), then use segmentation to move
ourselves to high addresses, and switch to C which uses high addresses
(through _START definition).
* i386/ldscript: Force mapping kernel at 0x100000, regardless of the value
of _START.
* i386/i386at/boothdr.S (boot_entry): Set up initial segments to project the
bootstrap linear space to high addresses.
Stick to binutils ELF scripts2012-03-14T00:24:15ZSamuel Thibaultsamuel.thibault@ens-lyon.org2012-03-14T00:24:15Zurn:sha1:5378113a56ef2bda1b2b9f594d250574ca697615
* i386/ldscript: Reformat to follow binutils version
Fix ifunc entries2010-09-14T01:55:11ZSamuel Thibaultsamuel.thibault@ens-lyon.org2010-09-14T01:51:22Zurn:sha1:faa99cfbe3dbac26021df620a19c3f671a0a2613
* i386/ldscript: Update to the version from binutils 2.20.51.20100617.
Remove SEARCH_DIR calls.
* Makefile.am (clib_routines): Accept undefined __rel_iplt_start and
__rel_iplt_end as these come from the ldscript.
* i386/i386at/boothdr.S (boot_entry): Call ifunc hooks at boot.
* i386/xen/xen_boothdr.S (start): Likewise.

* Makefile.am (gnumach_LINKFLAGS): New variable.
(gnumach_LINK): Use that one instead of the previously used
`LINKFLAGS_gnumach'.
* i386/Makefrag.am (LINKFLAGS_gnumach): Rename to `gnumach_LINKFLAGS',
move into [PLATFORM_at] and pass `_START'.
* i386/ldscript: Don't hardcode a _start address of 0x100000, but make
it configurable via `_START'.

`.text.start' first into `.text'.

GNU Binutils 2.16.1 installation.
