Hi I'm searching an alternative to "mstructure-size-option" for x86 32 bit instead of ARM. Background: I have C code which used to run on ARM with KEIL OS, we are porting this to linux (ARM and x86 32bit) Now due to the fact how the business logic of this software is, we need struct alignment of 4 bytes. this code shall not be changed as this is generated by a tool on the field (PLC software produced depending on the business case) I tried to use alignas(4) in the struct, and it seems to work, though I'm searching for a compiler flag that works everywhere without changing the source code (manually) -> 300k LoC ref: I asked already on stackoverflow https://stackoverflow.com/questions/55364009/gcc-similar-option-as-mstructure-size-option-for-x86-32-bit thanks
