- added portasm support for adding .section .note.GNU-stack "hints" marking generated .o files from assembly files as not needing an executable stack
* needed to be done manually in assembly files, in contrast to C translation units where gcc adds such hints automatically
* this is for security, and better/easier integration of dyncall into other projects and builds, as dyncall doesn't need an executable stack
* thanks to Thorsten Behrens for bringing this up to our intention and providing a first analysis
* currently only done on Linux, but will be added across other platforms (where applicable) after some testing

portasm - a toolkit for writing portable generic assembler sources ------------------------------------------------------------------ Copyright (C) 2011 Daniel Adler <dadler@uni-goettingen.de>. Licensed under BSD two-clause license. Requirements ------------ - C Preprocessor Supported Architectures and Tool-chains: ---------------------------------------- - x86: gas, apple as, masm - x64: gas, apple as, masm - ppc: gas, apple as - arm: gas, apple as Usage: ------ Implement assembler sources in *.S files which use C preprocessor. #include portasm-<ARCH>.S at front In order to generate MASM files for X86 and X64, run 'gen-masm.sh <name>' script which reads <name>.S and outputs <name>.masm file. Common Macros: -------------- BEGIN_ASM END_ASM BEGIN_PROC(name) END_PROC(name) GLOBAL(name) HEX(value)
