2017-11-03Prevent hipe_bs_validate_unicode from doing GCSverker Eriksson
Fix for x86_64 only. The calling native code can not handle a GC as it has a raw pointer where to write the binary data. If a GC happens the data (utf32) will be written to the old deallocated heap.

2016-06-30hipe: Fix bug in trap frame allocation wrappersMagnus Lång
The trap frame allocation wrappers occasionally call the garbage collector, even though built-in functions are not supposed to. On non-{x86,amd64} platforms, HiPE was optimising the BIF wrapper interface on the basis that BIFs do not GC. So, when hipe_reserve_beam_trap_frame called the garbage collector, the state in the PCB was stale and corruption happened. Now, these particular BIFs are reclassified as GC BIFs. Unfortunately, in order to do that we needed to introduce a gc_bif_interface_3 macro in every hipe_$ARCH_bifs.m4 file.

2015-04-22erts/hipe: unbreak arity 4 BIFsMikael Pettersson
This fixes arity 4 BIF support in HiPE, following its introduction on master (OTP 18) via the nox/ets-update_counter-4 merge. - define standard_bif_interface_4, nbif_4_gc_after_bif, and nbif_4_simple_exception on ARM: unbreaks the build on ARM - remove bogus stack re-alignment from standard_bif_interface_4 on AMD64: for 4-arg BIFs the stack is already aligned, and the code would misalign the C stack which violates the ABI and may cause alignment faults in vectorized code - the nbif_4_simple_exception OPD name on PPC64 was incorrectly using the nbif_3_simple_exception OPD name: this would have caused a multiple definition error in the assembler or linker In addition there are a few cleanups: - fix standard_bif_interface_N comment on x86 - fix standard_bif_interface_4 comment on SPARC - separate nbif_N_simple_exception blocks by empty lines on PPC, like on ARM, to clearly show which things belong together - fix standard_bif_interface_N comment on ARM - fix standard_bif_interface_4 on AMD64 to match the indentation and spacing conventions of the rest of that file

2014-10-24erts: Extend usage of ASM macro to avoid including asm macros in C codeSverker Eriksson
and reduce the probability of macro name collisions Catalyst: ppc macro "r0" conflicting with local variable in external.c
2014-08-16Fix HiPE debug lock checking on OS X 64bitAnthony Ramine
Position-independent code is mandatory on OS X. We use r11 as an intermediate register to fill BIF_P->hipe.bif_callee. This fixes the following error when doing `make debug FLAVOR=smp`: clang -cc1as: fatal error: error in backend: 32-bit absolute addressing is not supported in 64-bit mode

2012-11-13erts: Change assembler comment for hipe on x86 and amd64Sverker Eriksson
Previously done for ppc in c469d8ce14e9544a297d9af48c9da43137122d9a

2011-10-26erts-hipe: Enable debug compiled hipe-VM with lock checkerSverker Eriksson
Add hipe_debug_bif_wrapper() as a wrapper for every BIF called by native code.

2011-10-26erts-hipe: Adapt generated BIF wrappers for new calling conventionSverker Eriksson
x86 and amd64: Push BIF__ARGS array on C-stack. ppc, sparc and arm: Write BIF__ARGS array to P->def_arg_reg[] Just the simplest solution with limited assembler knowledge, probably room for improvements.
2011-10-26erts-hipe: Remove obscuring macros in generated assembler codeSverker Eriksson
No semantic change. Just easier to debug when jumps are spelled out and not obscured by yet another layer of macros.

* gc/hipe_darwin_amd64: Fix hipe memory allocation problems on darwin/amd64 Porting x86 darwin fixes to amd64 darwin hipe asm/m4 code Automatically enable hipe for darwin/amd64 builds Allow configure to enable_hipe for darwin/amd64 builds OTP-8416 HiPE now works in the 64-bit emulator on Mac OS X. (Thanks to Geoff Cant.)
2010-02-06Porting x86 darwin fixes to amd64 darwin hipe asm/m4 codeGeoff Cant
Compared to GNU as, Mac OS X's assembler uses different directives for text and global sections, and omits type and size directives entirely. We also need to mangle symbol names in order to allow linking with C object files.
