TARGET_SNAKE.
(umulsidi3): New pattern.

operand to emit_move_sequence.
(fp SImode load and store patterns): Move before main movsi

happen) or an SImode or DImode value into/out of a floating
point register.

REG_CLASS_FROM_LETTER): Define a new register class
FP_OR_SNAKE_FP_REGS, used only be reload_{in,out}{si,di}.

in HPUX 8.0.

linked with HPUX 8.0 shared libraries.
(TARGET_SWITCHES): New flags: -mshared-libs and -mno-shared-libs.

docs from HP were wrong.
(ASM_DECLARE_FUNCTION_NAME): Specify "ENTRY" param in .EXPORT
directive.
(ENCODE_SECTION_INFO): Encode function labels.
(ASM_OUTPUT_LABELREF): Deal with function labels.
(ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for
now; their only use (saving stuff during profiling) interacts in a
wierd way with required assembler directives at the start of a
function. Instead, do the save and restore in the function
prologue.
(hppa_encode_label): Declare.
* pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
libraries.
(LINK_SPEC): Don't link against shared libraries if debugging or
profiling.

sequences. Doing so greatly reduces the chance of running into a
HPUX linker bug when compiling kernels.
* pa.h (TARGET_KERNEL): New switch "-mkernel" which forces gcc to
avoid "ldil; add" sequences when %r29 and instead generate "addil"
