(JB_ELEMENT_SIZE, JB_PC): New defines.
(GET_LONGJMP_TARGET): Define.
(get_longjmp_target): Add prototype.
|
|
Provide `long double' support for most i386 targets.
* config/i386/tm-i386.h (TARGET_LONG_DOUBLE_FORMAT): Define as
&floatformat_i387_ext.
(TARGET_LONG_DOUBLE_BITS): Define as 96.
(REGISTER_VIRTUAL_TYPE): Change type for FPU registers to
`builtin_type_long_double'.
(REGISTER_CONVERT_TO_VIRTUAL): Call
i386_register_convert_to_virtual.
(REGISTER_CONVERT_TO_RAW): Call i386_register_convert_to_raw.
(i387_to_double, double_to_i387): Remove prototypes.
(i386_extract_return_value): Change prototype to match definition
in i386-tdep.c.
* config/i386/tm-i386mk.h (TARGET_LONG_DOUBLE_FORMAT): #undef.
(TARGET_LONG_DOUBLE_BITS): #undef.
* config/i386/tm-linux.h (TARGET_LONG_DOUBLE_BIT): Remove.
[HAVE_LONG_DOUBLE && HOST_I386] (LD_I387): Remove.
(i387_extract_floating, i387_store_floating): Remove prototypes.
(TARGET_EXTRACT_FLOATING, TARGET_STORE_FLOATING): Remove.
(REGISTER_CONVERT_TO_VIRTUAL, REGOISTER_CONVERT_TO_RAW): Remove.
(REGISTER_VIRTUAL_TYPE): Remove.
* i386-tdep.c (i386_register_convert_to_virtual): New function.
(i386_register_convert_to_raw): New function.
* i387-tdep.c [LD_I387] (i387_extract_floating): Remove.
(i387_store_floating): Remove.

* config/i386/tm-i386aix.h (I386_AIX_TARGET): Remove.
* config/i386/tm-linux.h (LOW_RETURN_REGNUM, HIGH_RETURN_REGNUM):
Remove
* i386-tdep.c (LOW_RETURN_REGNUM, HIGH_RETURN_REGNUM): New defines.
(i386_extract_return_value): Rewritten. Correctly support all
floating-point types and large integer types on targets that use
the standard i386 GDB register layout and return floating-point
values in the FPU.

LINUX_SIGTRAMP_INSN1, LINUX_SIGTRAMP_OFFSET1,
LINUX_SIGTRAMP_INSN2, LINUX_SIGTRAMP_OFFSET2, linux_sigtramp_code,
LINUX_SIGTRAMP_LEN, i386_linux_sigtramp_start,
LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0,
LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1,
linux_rt_sigtramp_code, LINUX_RT_SIGTRAMP_LEN,
i386_linux_rt_sigtramp_start, i386_linux_in_sigtramp,
i386_linux_sigcontext_addr, LINUX_SIGCONTEXT_PC_OFFSET,
i386_linux_sigtramp_saved_pc, LINUX_SIGCONTEXT_SP_OFFSET,
i386_linux_sigtramp_saved_sp): Deleted. These all implement
Linux-specific signal trampoline detection, and should be moved to...
* i386-linux-nat.c: ... here.
* config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define
this any more, since we're not enabling OS-specific code in a
OS-independent file.

|
* i386-tdep.c (i386_linux_saved_pc_after_call): New function.
* config/i386/tm-linux.h (SAVED_PC_AFTER_CALL): Define to call
i386_linux_saved_pc_after_call.

Fix support for Linux/i386 signal trampolines. The old approach
didn't work for Linux 2.2 and beyond, and didn't work with recent
versions of the GNU C library.
* i386-tdep.c (LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0,
LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1): New defines.
(linux_rt_sigtramp_code): New variable.
(LINUX_RT_SIGTRAMP_LEN): New define.
(i386_linux_rt_sigtramp_start): New function. Detect start of
signal trampolines for RT signals.
(i386_linux_sigtramp): Removed.
(i386_linux_in_sigtramp): New function.
(i386_linux_sigcontext_addr): New function. Recognize the names
of the signal tranmpolines used by recent versions of the GNU C
library, and add support for RT signals.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): New
defines. Moved here from config/i386/tm-linux.h.
(i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp):
Reimplement in terms of i386_linux_sigcontext_addr.
* config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Removed.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):
Moved to i386-tdep.c.
(IN_SIGTRAMP): Redefine to call i386_linux_in_sigtramp.
