Vladimir Serbinenko f1b3525385 Add -mno-stack-arg-probe on mingw. 
This argument disables generation of calls to __chkstk_ms. Those calls are
useless on GRUB as function is dummy. Yet they increase module size and
use limited-range relocations which may not work under some memory layouts.
We currently don't use such layouts on concerned platforms but lt's correct
this.

Vladimir Serbinenko 68e158dffd Strip .ARM.exidx 
This section is generated by clang and is useful only for debugging.
It contains exotic relocations, so strip them to avoid them interferring
with module loading.
 2015-12-31 18:13:59 +01:00
Vladimir Serbinenko e1b2b9bf1d module-verifier: Check range-limited relative relocations. 
Check that they point to the same module, so will end up in the same
chunk of memory.

Vladimir Serbinenko 76588d1319 xen/relocator: Use local symbol to ensure that code is relocation-free. 2015-12-31 14:54:56 +01:00

Vladimir Serbinenko 5919626c90 sparc64: Fix assembly to let compiler to fill in memory references. 
This fixes the use of not fully relocatable (they assume that variables are
under 4G limit in virtual memory) references.
 2015-12-31 13:07:16 +01:00
Vladimir Serbinenko 79cfad6fbe backtrace: Remove assembly assumption that grub_backtrace_pointer is under 4G 2015-12-30 18:19:44 +01:00

Vladimir Serbinenko 4111882828 grub-mount: Fix oath parsing. 
Brackets detection was copied from somewhere else and makes no sense in case
of grub-mount and prevents user from accessing and files with ) in them.

Vladimir Serbinenko d43a5ee651 tsc: Use alternative delay sources whenever appropriate. 
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.

Based on patch by Michael Chang.

Vladimir Serbinenko 323ef2bdc3 asm-tests/i386-pc: Check that near jumps are 2 bytes. 
We already check that jump over 300 bytes gap is 3 bytes in code16-mode.
Some clang versions generate 3-byte opcode for short jumps which makes
boot.img blow over 512-byte limit. Enforce -no-integrated-as in such cases

Vladimir Serbinenko d3b464a7c0 archelp: Never pass NULL as mtime.

 2015-07-27 13:19:02 +02:00
Vladimir Serbinenko 5fb1e859f7 HFS: Convert to fshelp. 
HFS doesn't handle "." and ".." properly. Convert it to fshelp to reuse the
logic.

Vladimir Serbinenko bfb5b33e96 FAT: Convert to fshelp. 
exFAT doesn't handle "." and ".." correctly, convert it to fshelp to

BFS doesn't handle ".." correctly, so convert it to fshelp to reuse the logic.
 2015-07-27 12:48:38 +02:00
Vladimir Serbinenko fa93b0e4f5 fshelp: Add handling of "." and ".." and grub_fshelp_find_file_lookup. 
Recent tests have discovered that many of our filesystems have flawed
handling of "." and "..". Rather than attempting to fix it in filesystems
themselves, make the common code fshelp aware of "." and ".." and handle
them in this layer. Add grub_fshelp_find_file_lookup for easy conversion
of BFS, HFS and exFAT which have the same problem and don't use fshelp.
 2015-07-27 12:45:35 +02:00
Vladimir Serbinenko 4622f4e1ee Switch procfs to use archelp. 
This fixes handling of "." and "..".

Given special semantics of ZFS it's far from clear what the expected
result is. Just skip it for now

Resulting binary is unchanged as it happens we were already aligned
by chance.

Vladimir Serbinenko 80783ea646 fwstart: Replace blt with bltz. 
blt A, $zero, B and bltz A, B are equivalent but clang recognizes only
later, so use it.

Resulting binary is unchanged.

Vladimir Serbinenko eecdbebc84 Remove mips_attributes. 
mips_attributes was introduced to work around clang problems with
-msoft-float. Those problems are now fixed and moreover .gnu_attributes
itself is unportable and creates problem with clang.

Revert "mips: Fix soft-float handling."

This partially reverts commit 6a4ecd276e.

Vladimir Serbinenko c856be6bca multiboot1: never place modules in low memory. 
While in theory permitted by the spec, modules rarely fit in low memory
anyway and not every kernel is able to handle modules in low memory anyway.
At least VMWare is known not to be able to handle modules at arbitrary
locations.

Vladimir Serbinenko 63034d3261 arp, icmp: Fix handling in case of oversized or invalid packets. 
This restrict ARP handling to MAC and IP addresses but in practice we need

Vladimir Serbinenko 064360e667 Remove libgcc dependency. 
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.
