That means we need to know -the symbolic names & values of all signals that might be sent. - -The tools that generate that list use signal.h and include all -symbols that start with "SIG" so as to automatically include any -new symbols that the C library might add. Unfortunately, this -also picks up "SIGSTKSZ" which is not actually a signal itself, -but a signal related setting -- it's the size of the stack when -a signal is handled. - -By itself this doesn't super matter as we will never see a signal -with that same value (since the range of valid signals tend to be -way less than 1024, and the size of the default signal stack will -never be that small). But with recent glibc changes that make this -into a dynamic value instead of a compile-time constant, some users -see build failures when building the sim. - -As suggested by Adam Sampson, update our scripts to ignore this -symbol to simplify everything and avoid the build failure. - -Bug: https://sourceware.org/PR28302 ---- - sim/bfin/linux-targ-map.h | 5 +---- - sim/common/gennltvals.py | 6 ++++-- - sim/common/nltvals.def | 1 - - 3 files changed, 5 insertions(+), 7 deletions(-) - -diff --git a/sim/bfin/linux-targ-map.h b/sim/bfin/linux-targ-map.h -index e9c8c8f273b..0340ed54764 100644 ---- a/sim/bfin/linux-targ-map.h -+++ b/sim/bfin/linux-targ-map.h -@@ -30,6 +30,7 @@ echo - # XXX: nothing uses this ? - echo '#include <signal.h>' | \ - bfin-uclinux-gcc -E -dD -P - | \ -+grep -v SIGSTKSZ | \ - sed -r -n \ - -e '1istatic CB_TARGET_DEFS_MAP cb_linux_signal_map[] = {' \ - -e '$i\ \ { 0, -1, -1 }\n};' \ -@@ -1987,10 +1988,6 @@ static CB_TARGET_DEFS_MAP cb_linux_signal_map[] = - #ifdef SIG_SETMASK - # define TARGET_LINUX_SIG_SETMASK 2 - { "SIG_SETMASK", SIG_SETMASK, TARGET_LINUX_SIG_SETMASK }, --#endif --#ifdef SIGSTKSZ --# define TARGET_LINUX_SIGSTKSZ 8192 -- { "SIGSTKSZ", SIGSTKSZ, TARGET_LINUX_SIGSTKSZ }, - #endif - { 0, -1, -1 } - }; -diff --git a/sim/common/gennltvals.py b/sim/common/gennltvals.py -index db3ff641d40..955ace34311 100755 ---- a/sim/common/gennltvals.py -+++ b/sim/common/gennltvals.py -@@ -67,6 +67,7 @@ FILE_HEADER = f"""\ - def gentvals(output: TextIO, cpp: str, srctype: str, srcdir: Path, - headers: Iterable[str], - pattern: str, -+ filter: str = r'^$', - target: str = None): - """Extract constants from the specified files using a regular expression. - -@@ -94,12 +95,13 @@ def gentvals(output: TextIO, cpp: str, srctype: str, srcdir: Path, - srcfile = ''.join(f'#include <{x}>\n' for x in headers) - syms = set() - define_pattern = re.compile(r'^#\s*define\s+(' + pattern + ')') -+ filter_pattern = re.compile(filter) - for header in headers: - with open(srcdir / header, 'r', encoding='utf-8') as fp: - data = fp.read() - for line in data.splitlines(): - m = define_pattern.match(line) -- if m: -+ if m and not filter_pattern.search(line): - syms.add(m.group(1)) - for sym in sorted(syms): - srcfile += f'#ifdef {sym}\nDEFVAL {{ "{sym}", {sym} }},\n#endif\n' -@@ -129,7 +131,7 @@ def gen_common(output: TextIO, newlib: Path, cpp: str): - ('errno.h', 'sys/errno.h'), 'E[A-Z0-9]*') - - gentvals(output, cpp, 'signal', newlib / 'newlib/libc/include', -- ('signal.h', 'sys/signal.h'), r'SIG[A-Z0-9]*') -+ ('signal.h', 'sys/signal.h'), r'SIG[A-Z0-9]*', filter=r'SIGSTKSZ') - - gentvals(output, cpp, 'open', newlib / 'newlib/libc/include', - ('fcntl.h', 'sys/fcntl.h', 'sys/_default_fcntl.h'), r'O_[A-Z0-9]*') -diff --git a/sim/common/nltvals.def b/sim/common/nltvals.def -index 8ae88397249..8bc6ae59026 100644 ---- a/sim/common/nltvals.def -+++ b/sim/common/nltvals.def -@@ -116,7 +116,6 @@ - { "SIGPROF", 27 }, - { "SIGQUIT", 3 }, - { "SIGSEGV", 11 }, -- { "SIGSTKSZ", 8192 }, - { "SIGSTOP", 17 }, - { "SIGSYS", 12 }, - { "SIGTERM", 15 }, --- -2.27.0 - |
