* Remove make preinstallChris Johns2018-01-251-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
* pc386: Simplify bsp_specsJoel Sherrill2017-12-191-5/+1
| | | | | | | | If this has any issues, check that the change in linking the 16-bit startup code in Makefile.am generates the same code. This was odd code and didn't need the RTEMS linkcmds anyway. Updates #3520.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Done: arm bfin epiphany i386 lm32 m32c mips moxie nios2 or1k powerpc riscv sh sparc sparc64 v850 To do: m68k Differences noted: + endfile was sometimes before startfile + endfile sometimes was hard-coded and did not have -qrtems version + Should -e XXX (e.g. entry point) be in linkcmds? + Should -u XXX (e.g. undefined symbols) be in linkcmds? + Typos: Odd spacing, "old_endfiles" typo, and *(old_endfiles) (not %) + nios2: Referenced crtnn.o not crtn.o (error) Need to revisit: + m32c, moxie, sparc64 includes !nostdlib which is not used elsewhere + sh has -EL/-EB mapping. Why needed? + sparc64 didn't include crti.o/crtn.o but it is part of toolset + v850 uses something like this for link and end_file: "%{qrtems: %(old_link)}" This means that these are unnecessary. Try this on all. + mips uses old_link all the time also. + arm/tms750 adds -EB. + powerpc: Why do we have rtems_crt* and not use something from GCC? Updates #3520.

* Moved -qnolinkcmds option so arguments passed on the command line areJoel Sherrill1997-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | interpreted at the right point per Eric Norum's discovery: The problem with the my previous `fix' for adding linker commands was with the ordering of the options to the linker. For example, to make a larger heap size, the application Makefile would CFLAGS_LD = -Wl,--defsym -Wl,HeapSize=0x40000 The command passed to the linker would be : m68k-rtems-ld .... -T xxx/linkcmds .... --defsym HeapSize=0x40000 ..... This doesn't work because the script in linkcmds inserts a default value for HeapSize if HeapSize is not defined by the time the linker looks at the linkcmds script. The solution seems to be to move the -T linkcmds%s in the bsp_specs file out of the link specfication and into the lib specification -- a little unorthodox, perhaps, but it seems to work!
